    Abstract
    The BAER Web Resources Group was charged in October 1999 with defining and describing the parameters of electronic resources that do not clearly belong to the categories being defined by the BAER Digital Group or the BAER Electronic Journals Group. After some difficulty identifying precisely which resources fell under the Group's charge, we finally named the following types of resources for our consideration: web sites, electronic texts, indexes, databases and abstracts, online reference resources, and networked and non-networked CD-ROMs. Electronic resources are a vast and growing collection that touch nearly every department within the Library. It is unrealistic to think one department can effectively administer all aspects of the collection. The Group then began to focus on the concern of bibliographic access to these varied resources, and to define parameters for handling or processing them within the Library. Some key elements became evident as the work progressed. * Selection process of resources to be acquired for the collection * Duplication of effort * Use of CORC * Resource Finder design * Maintenance of Resource Finder * CD-ROMs not networked * Communications * Voyager search limitations. An unexpected collaboration with the Web Development Committee on the Resource Finder helped to steer the Group to more detailed descriptions of bibliographic access. This collaboration included development of data elements for the Resource Finder database, and some discussions on Library staff processing of the resources. The Web Resources Group invited expert testimony to help the Group broaden its view to envision public use of the resources and discuss concerns related to technical services processing. The first testimony came from members of the Resource Finder Committee. Some background information on the Web Development Resource Finder Committee was shared. The second testimony was from librarians who select electronic texts. Three main themes were addressed: accessing CD-ROMs; the issue of including non-networked CD-ROMs in the Resource Finder; and, some special concerns about electronic texts. The third testimony came from librarians who select indexes and abstracts and also provide Reference services. Appendices to this report include minutes of the meetings with the experts (Appendix A), a list of proposed data elements to be used in the Resource Finder (Appendix B), and recommendations made to the Resource Finder Committee (Appendix C). Below are summaries of the key elements.

    Abstract
    The National Science Foundation's (NSF) National Science, Mathematics, Engineering, and Technology Education Digital Library (NSDL) program seeks to create, develop, and sustain a national digital library supporting science, mathematics, engineering, and technology (SMET) education at all levels -- preK-12, undergraduate, graduate, and life-long learning. The resulting virtual institution is expected to catalyze and support continual improvements in the quality of science, mathematics, engineering, and technology (SMET) education in both formal and informal settings. The vision for this program has been explored through a series of workshops over the past several years and documented in accompanying reports and monographs. (See [1-7, 10, 12, and 13].) These efforts have led to a characterization of the digital library as a learning environments and resources network for science, mathematics, engineering, and technology education, that is: * designed to meet the needs of learners, in both individual and collaborative settings; * constructed to enable dynamic use of a broad array of materials for learning primarily in digital format; and * managed actively to promote reliable anytime, anywhere access to quality collections and services, available both within and without the network. Underlying the NSDL program are several working assumptions. First, while there is currently no lack of "great piles of content" on the Web, there is an urgent need for "piles of great content". The difficulties in discovering and verifying the authority of appropriate Web-based material are certainly well known, yet there are many examples of learning resources of great promise available (particularly those exploiting the power of multiple media), with more added every day. The breadth and interconnectedness of the Web are simultaneously a great strength and shortcoming. Second, the "unit" or granularity of educational content can and will shrink, affording the opportunity for users to become creators and vice versa, as learning objects are reused, repackaged, and repurposed. To be sure, this scenario cannot take place without serious attention to intellectual property and digital rights management concerns. But new models and technologies are being explored (see a number of recent articles in the January issue of D-Lib Magazine). Third, there is a need for an "organizational infrastructure" that facilitates connections between distributed users and distributed content, as alluded to in the third bullet above. Finally, while much of the ongoing use of the library is envisioned to be "free" in the sense of the public good, there is an opportunity and a need to consider multiple alternative models of sustainability, particularly in the area of services offered by the digital library. More details about the NSDL program including information about proposal deadlines and current awards may be found at <http://www.ehr.nsf.gov/ehr/due/programs/nsdl>.

    Abstract
    Based on a decade's experience with the Alexandria Digital Library Project, seven issues are presented that arise in creating georeferenced digital libraries, and that appear to be intrinsic to the problem of creating any library-like information system that operates on georeferenced and geospatial resources. The first and foremost issue is providing discovery of georeferenced resources. Related to discovery are the issues of gazetteer integration and specialized ranking of search results. Strong data typing and scalability are implementation issues. Providing spatial context is a critical user interface issue. Finally, sophisticated resource access mechanisms are necessary to operate on geospatial resources.

    Abstract
    The European Commission's goal for Europeana is to make European information resources easier to use in an online environment. It will build on Europe's rich heritage, combining multicultural and multilingual environments with technological advances and new business models. The Europeana prototype is the result of a 2-year project that began in July 2007. Europeana.eu went live on 20 November 2008, launched by Viviane Reding, European Commissioner for Information Society and Media. Europeana.eu is about ideas and inspiration. It links the user to 2 million digital items: images, text, sounds and videos. Europeana is a Thematic Network funded by the European Commission under the eContentplus programme, as part of the i2010 policy. Originally known as the European digital library network - EDLnet - it is a partnership of 100 representatives of heritage and knowledge organisations and IT experts from throughout Europe. They contribute to the work packages that are solving the technical and usability issues. The project is run by a core team based in the national library of the Netherlands, the Koninklijke Bibliotheek. It builds on the project management and technical expertise developed by The European Library, which is a service of the Conference of European National Librarians. Content is added via so called aggregators, national or domain specific portals aggegrating digital content and channelling it to Europeana. Most of these portals are being developed in the framework of EU funded projects, e.g. European Film Gateway, Athena and EuropeanaLocal. Overseeing the project is the EDL Foundation, which includes key European cultural heritage associations from the four domains. The Foundation's statutes commit members to: * providing access to Europe's cultural and scientific heritage through a cross-domain portal; * co-operating in the delivery and sustainability of the joint portal; * stimulating initiatives to bring together existing digital content; * supporting digitisation of Europe's cultural and scientific heritage. Europeana.eu is a prototype. Europeana Version 1.0 is being developed and will be launched in 2010 with links to over 6 million digital objects.

    Abstract
    For those building digital library services, the organisational barriers are sometimes far more intractable than technological issues. This was firmly flagged in one of the first workshops focusing specifically on the digital library research agenda: Digital libraries are not simply technological constructs; they exist within a rich legal, social, and economic context, and will succeed only to the extent that they meet these broader needs. The innovatory drive within the development of digital library services thrives on the tension between meeting both technical and social imperatives. The Renardus project partners have previously taken parts in projects establishing the technical basis for subject gateways (e.g., ROADS, DESIRE], EELS) and are aware that technical barriers to interoperability are outweighed by challenges relating to the organisational and business models used. Within the Renardus project there has been a determination to address these organisational and business issues from the beginning. Renardus intends initially to create a pilot service, targeting the European scholar with a single point of access to quality selected Web resources. Looking ahead beyond current project funding, it aims to create the organisational and technological infrastructure for a sustainable service. This means the project is concerned with the range of processes required to establish a viable service, and is explicitly addressing business issues as well as providing a technical infrastructure. The overall aim of Renardus is to establish a collaborative framework for European subject gateways that will benefit both users in terms of enhanced services, and the gateways themselves in terms of shared solutions. In order to achieve this aim, Renardus will provide firstly a pilot service for the European academic and research communities brokering access to those European-based information gateways that currently participate in the project; in other words, brokering to gateways that are already in existence. Secondly the project will explore ways to establish the organisational basis for co-operative efforts such as metadata sharing, joint technical solutions and agreement on standardisation. It is intended that this exploration will feed back valuable experience to the individual participating gateways to suggest ways their services can be enhanced.
    Funding from the UK Electronic Libraries (eLib) programme and the European Community's Fourth Framework programme assisted the initial emergence of information gateways (e.g., SOSIG, EEVL, OMNI in the UK, and EELS in Sweden). Other gateways have been developed by initiatives co-ordinated by national libraries (such as DutchESS in the Netherlands, and AVEL and EdNA in Australia) and by universities and research funding bodies (e.g., GEM in the US, the Finnish Virtual Library, and the German SSG-FI services). An account of the emergence of subject gateways since the mid-1990s by Dempsey gives an historical perspective -- informed by UK experience in particular -- and also considers the future development of subject gateways in relation to other services. When considering the development and future of gateways, it would be helpful to have a clear definition of the service offered by a so-called 'subject gateway'. Precise definitions of 'information gateways', 'subject gateways' and 'quality controlled subject gateways' have been debated elsewhere. Koch has reviewed definitions and suggested typologies that are useful, not least in showing the differences that exist between broadly similar services. Working definitions that we will use in this article are that a subject gateway provides a search service to high quality Web resources selected from a particular subject area, whereas information gateways have a wider criteria for selection of resources, e.g., a national approach. Inevitably in a rapidly changing international environment different people perceive different emphases in attempts to label services, the significant issue is that users, developers and designers can recognise and benefit from commonalties in approach.
    The Renardus project has brought together gateways that are 'large-scale national initiatives'. Within the European context this immediately introduces a diversity of organisations, as responsibility for national gateway initiatives is located differently, for example, in national libraries, national agencies with responsibility for educational technology infrastructure, and within universities or consortia of universities. Within the project, gateways are in some cases represented directly by their own personnel, in some cases by other departments or research centres, but not always by the people responsible for providing the gateway service. For example, the UK Resource Discovery Network (RDN) is represented in the project by UKOLN (formerly part of the Resource Discovery Network Centre) and the Institute of Learning and Research Technology (ILRT), University of Bristol -- an RDN 'hub' service provider -- who are primarily responsible for dissemination. Since the start of the project there have been changes within the organisational structures providing gateways and within the service ambitions of gateways themselves. Such lack of stability is inherent within the Internet service environment, and this presents challenges to Renardus activity that has to be planned for a three-year period. For example, within the gateway's funding environment there is now an exploration of 'subject portals' offering more extended services than gateways. There is also potential commercial interest for including gateways as a value-added component to existing commercial services, and new offerings from possible competitors such as Google's Web Directory and country based services. This short update on the Renardus project intends to inform the reader of progress within the project and to give some wider context to its main themes by locating the project within the broader arena of digital library activity. There are twelve partners in the project from Denmark, Finland, France, Germany, the Netherlands and Sweden, as well as the UK. In particular we will focus on the specific activity in which UKOLN is involved: the architectural design, the specification of functional requirements, reaching consensus on a collaborative business model, etc. We will also consider issues of metadata management where all partners have interests. We will highlight implementation issues that connect to areas of debate elsewhere. In particular we see connections with activity related to establishing architectural models for digital library services, connections to the services that may emerge from metadata sharing using the Open Archives Initiative metadata sharing protocol, and links with work elsewhere on navigation of digital information spaces by means of controlled vocabularies.

    Abstract
    The explosive growth of literature and data in the life sciences challenges researchers to keep track of current advancements in their disciplines. Novel approaches in the life science like the One Health paradigm require integrated methodologies in order to link and connect heterogeneous information from databases and literature resources. Current publications in the life sciences are increasingly characterized by the employment of trans-disciplinary methodologies comprising molecular and cell biology, genetics, genomic, epigenomic, transcriptional and proteomic high throughput technologies with data from humans, plants, and animals. The literature search engine LIVIVO empowers retrieval functionality by incorporating various literature resources from medicine, health, environment, agriculture and nutrition. LIVIVO is developed in-house by ZB MED - Information Centre for Life Sciences. It provides a user-friendly and usability-tested search interface with a corpus of 55 Million citations derived from 50 databases. Standardized application programming interfaces are available for data export and high throughput retrieval. The search functions allow for semantic retrieval with filtering options based on life science entities. The service oriented architecture of LIVIVO uses four different implementation layers to deliver search services. A Knowledge Environment is developed by ZB MED to deal with the heterogeneity of data as an integrative approach to model, store, and link semantic concepts within literature resources and databases. Future work will focus on the exploitation of life science ontologies and on the employment of NLP technologies in order to improve query expansion, filters in faceted search, and concept based relevancy rankings in LIVIVO.

    Abstract
    This article describes two approaches for searching heterogeneous resources, which are explained as they are used in two corresponding existing systems-RIRS (Resource Integration Retrieval System) and HRUSP (Heterogeneous Resource Union Search Platform). On analyzing the existing systems, a possible framework-the MUSP (Multimetadata-Based Union Search Platform) is presented. Libraries now face a dilemma. On one hand, libraries subscribe to many types of database retrieval systems that are produced by various providers. The libraries build their data and information systems independently. This results in highly heterogeneous and distributed systems at the technical level (e.g., different operating systems and user interfaces) and at the conceptual level (e.g., the same objects are named using different terms). On the other hand, end users want to access all these heterogeneous data via a union interface, without having to know the structure of each information system or the different retrieval methods used by the systems. Libraries must achieve a harmony between information providers and users. In order to bridge the gap between the service providers and the users, it would seem that all source databases would need to be rebuilt according to a uniform data structure and query language, but this seems impossible. Fortunately, however, libraries and information and technology providers are now making an effort to find a middle course that meets the requirements of both data providers and users. They are doing this through resource integration.

    Abstract
    A subject gateway, in the context of network-based resource access, can be defined as some facility that allows easier access to network-based resources in a defined subject area. The simplest types of subject gateways are sets of Web pages containing lists of links to resources. Some gateways index their lists of links and provide a simple search facility. More advanced gateways offer a much enhanced service via a system consisting of a resource database and various indexes, which can be searched and/or browsed through a Web-based interface. Each entry in the database contains information about a network-based resource, such as a Web page, Web site, mailing list or document. Entries are usually created by a cataloguer manually identifying a suitable resource, describing the resource using a template, and submitting the template to the database for indexing. Subject gateways are also known as subject-based information gateways (SBIGs), subject-based gateways, subject index gateways, virtual libraries, clearing houses, subject trees, pathfinders and other variations thereof. This paper describes the characteristics of some of the subject gateways currently accessible through the Web, and compares them to automatic "vacuum cleaner" type search engines, such as AltaVista. The application of WHOIS++, centroids, query routing, and forward knowledge to searching several of these subject gateways simultaneously is outlined. The paper concludes with looking at some of the issues facing subject gateway development in the near future. The paper touches on many of the issues mentioned in a previous paper in D-Lib Magazine, especially regarding resource-discovery related initiatives and services.

    Abstract
    In fall 2004, the National Science Foundation's (NSF) National Science, Technology, Engineering, and Mathematics Education Digital Library (NSDL) program made new grants in three tracks: Pathways, Services, and Targeted Research. Together with projects started in fiscal years (FY) 2000-03 these new grants continue the development of a national digital library of high quality educational resources to support learning at all levels in science, technology, engineering, and mathematics (STEM). By enabling broad access to reliable and authoritative learning and teaching materials and associated services in a digital environment, the National Science Digital Library expects to promote continual improvements in the quality of formal STEM education, and also to serve as a resource for informal and lifelong learning. Proposals for the FY05 funding cycle are due April 11, 2005, and the full solicitation is available at <http://www.nsf.gov/publications/pub_summ.jsp?ods_key=nsf05545>. Two NSF directorates, the Directorate for Geosciences (GEO) and the Directorate for Mathematical and Physical Sciences (MPS) have both provided significant co-funding for over twenty projects in the first four years of the program, illustrating the NSDL program's facilitation of the integration of research and education, an important strategic objective of the NSF. In FY2004, the NSDL program introduced a new Pathways track, replacing the earlier Collections track. The Services track strongly encouraged two particular types of projects: (1) selection services and (2) usage development workshops. * Pathways projects provide stewardship for educational content and services needed by a broad community of learners; * Selection services projects identify and increase the high-quality STEM educational content known to NSDL; and * Usage development workshops engage new communities of learners in the use of NSDL and its resources.
    These three elements reflect a refinement of NSDL's initial emphasis on collecting educational resources, materials, and other digital learning objects, towards enabling learners to "connect" or otherwise find pathways to resources appropriate to their needs. Projects are also developing both the capacities of individual users and the capacity of larger communities of learners to use and contribute to NSDL. For the FY2004 funding cycle, one hundred forty-four proposals sought approximately $126.5 million in total funding. Twenty-four new awards were made with a cumulative budget of approximately $10.2 million. These include four in the Pathways track, twelve in the Services track, and eight in the Targeted Research track. As in the earlier years of the program, sister directorates to the NSF Directorate for Education and Human Resources (EHR) are providing significant co-funding of projects. Participating directorates for FY2004 are GEO and MPS. Within EHR, the Advanced Technological Education program and the Experimental Program to Stimulate Competitive Research are also co-funding projects. Complete information on the technical and organizational progress of NSDL including links to current Standing Committees and community workspaces may be found at <http://nsdl.org/community/nsdlgroups.php>. All workspaces are open to the public, and interested organizations and individuals are encouraged to learn more about NSDL and join in its development. Following is a list of the new FY04 awards displaying the official NSF award number, the project title, the grantee institution, and the name of the Principal Investigator (PI). A condensed description of the project is also included. Full abstracts are available from the NSDL program site (under Related URLs see the link to NSDL program site (under Related URLs see the link to Abstracts of Recent Awards Made Through This Program.) The projects are displayed by track and are listed by award number. In addition, seven of these projects have explicit relevance to applications to pre-K to 12 education (indicated with a * below). Four others have clear potential for application to the pre-K to 12 arena (indicated with a ** below).

    Abstract
    The Electronic Cultural Atlas Initiative was formed to encourage scholarly communication and the sharing of data among researchers who emphasize the relationships between place, time, and topic in the study of culture and history. In an effort to develop better tools and practices, The Electronic Cultural Atlas Initiative has sponsored the collaborative development of software for downloading and editing geo-temporal data to create dynamic maps, a clearinghouse of shared datasets accessible through a map-based interface, projects on format and content standards for gazetteers and time period directories, studies to improve geo-temporal aspects in online catalogs, good practice guidelines for preparing e-publications with dynamic geo-temporal displays, and numerous international conferences. The Electronic Cultural Atlas Initiative (ECAI) grew out of discussions among an international group of scholars interested in religious history and area studies. It was established as a unit under the Dean of International and Area Studies at the University of California, Berkeley in 1997. ECAI's mission is to promote an international collaborative effort to transform humanities scholarship through use of the digital environment to share data and by placing greater emphasis on the notions of place and time. Professor Lewis Lancaster is the Director. Professor Michael Buckland, with a library and information studies background, joined the effort as Co-Director in 2000. Assistance from the Lilly Foundation, the California Digital Library (University of California), and other sources has enabled ECAI to nurture a community; to develop a catalog ("clearinghouse") of Internet-accessible georeferenced resources; to support the development of software for obtaining, editing, manipulating, and dynamically visualizing geo-temporally encoded data; and to undertake research and development projects as needs and resources determine. Several hundred scholars worldwide, from a wide range of disciplines, are informally affiliated with ECAI, all interested in shared use of historical and cultural data. The Academia Sinica (Taiwan), The British Library, and the Arts and Humanities Data Service (UK) are among the well-known affiliates. However, ECAI mainly comprises individual scholars and small teams working on their own small projects on a very wide range of cultural, social, and historical topics. Numerous specialist committees have been fostering standardization and collaboration by area and by themes such as trade-routes, cities, religion, and sacred sites.

    Abstract
    Do a search on AltaVista for "algebra". What do you get? Nearly 700,000 hits, of which AltaVista will allow you to view only what it determines is the top 200. Major search engines such as AltaVista, Excite, HotBot, Lycos, and the like continue to provide a valuable service, but with the recent growth of the Internet, topic-specific sites that provide some organization to the topic are increasingly important. It the goal of the Mathematics Archives to make it easier for the ordinary user to find useful mathematical information on the Web. The Mathematics Archives (http://archives.math.utk.edu) is a multipurpose site for mathematics on the Internet. The focus is on materials which can be used in mathematics education (primarily at the undergraduate level). Resources available range from shareware and public domain software to electronic proceedings of various conferences, to an extensive collection of annotated links to other mathematical sites. All materials on the Archives are categorized and cross referenced for the convenience of the user. Several search mechanisms are provided. The Harvest search engine is implemented to provide a full text search of most of the pages on the Archives. The software we house and our list of annotated links to mathematical sites are both categorized by subject matter. Each of these collections has a specialized search engine to assist the user in locating desired material. Services at the Mathematics Archives are divided up into five broad topics: * Links organized by Mathematical Topics * Software * Teaching Materials * Other Math Archives Features * Other Links

    Abstract
    As digital libraries become a major source of information for many people, we need to know more about how people seek and retrieve information in digital environments. Quite commonly, users with a problem-at-hand and associated question-in-mind repeatedly search a literature for answers, and seek information in stages over extended periods from a variety of digital information resources. The process of repeatedly searching over time in relation to a specific, but possibly an evolving information problem (including changes or shifts in a variety of variables), is called the successive search phenomenon. The study outlined in this paper is currently investigating this new and little explored line of inquiry for information retrieval, Web searching, and digital libraries. The purpose of the research project is to investigate the nature, manifestations, and behavior of successive searching by users in digital environments, and to derive criteria for use in the design of information retrieval interfaces and systems supporting successive searching behavior. This study includes two related projects. The first project is based in the School of Library and Information Sciences at the University of North Texas and is funded by a National Science Foundation POWRE Grant <http://www.nsf.gov/cgi-bin/show?award=9753277>. The second project is based at the Department of Information Studies at the University of Sheffield (UK) and is funded by a grant from the British Library <http://www.shef. ac.uk/~is/research/imrg/uncerty.html> Research and Innovation Center. The broad objectives of each project are to examine the nature and extent of successive search episodes in digital environments by real users over time. The specific aim of the current project is twofold: * To characterize progressive changes and shifts that occur in: user situational context; user information problem; uncertainty reduction; user cognitive styles; cognitive and affective states of the user, and consequently in their queries; and * To characterize related changes over time in the type and use of information resources and search strategies particularly related to given capabilities of IR systems, and IR search engines, and examine changes in users' relevance judgments and criteria, and characterize their differences. The study is an observational, longitudinal data collection in the U.S. and U.K. Three questionnaires are used to collect data: reference, client post search and searcher post search questionnaires. Each successive search episode with a search intermediary for textual materials on the DIALOG Information Service is audiotaped and search transaction logs are recorded. Quantitative analysis includes statistical analysis using Likert scale data from the questionnaires and log-linear analysis of sequential data. Qualitative methods include: content analysis, structuring taxonomies; and diagrams to describe shifts and transitions within and between each search episode. Outcomes of the study are the development of appropriate model(s) for IR interactions in successive search episodes and the derivation of a set of design criteria for interfaces and systems supporting successive searching.

    Abstract
    The author holds a chair in Humanities Computer Science at the University of Cologne. For a number of years, he has been responsible for digitization projects, either as project director or as the person responsible for the technology being employed on the projects. The "Duderstadt project" (http://www.archive.geschichte.mpg.de/duderstadt/dud-e.htm) is one such project. It is one of the early large-scale manuscript servers, finished at the end of 1998, with approximately 80,000 high resolution documents representing the holdings of a city archive before the year 1600. The digital library of the Max-Planck-Institut für Europäische Rechtsgeschichte in Frankfurt (http://www.mpier.uni-frankfurt.de/dlib) is another project on which the author has worked, with currently approximately 900,000 pages. The author is currently project director of the project "Codices Electronici Ecclesiae Colonensis" (CEEC), which has just started and will ultimately consist of approximately 130,000 very high resolution color pages representing the complete holdings of the manuscript library of a medieval cathedral. It is being designed in close cooperation with the user community of such material. The project site (http://www.ceec.uni-koeln.de), while not yet officially opened, currently holds about 5,000 pages and is growing by 100 - 150 pages per day. Parallel to the CEEC model project, a conceptual project, the "Codex Electronicus Colonensis" (CEC), is at work on the definition of an abstract model for the representation of medieval codices in digital form. The following paper has grown out of the design considerations for the mentioned CEC project. The paper reflects a growing concern of the author's that some of the recent advances in digital (research) libraries are being diluted because it is not clear whether the advances really reach the audience for whom the projects would be most useful. Many, if not most, digitization projects have aimed at existing collections as individual servers. A digital library, however, should be more than a digitized one. It should be built according to principles that are not necessarily the same as those employed for paper collections, and it should be evaluated according to different measures which are not yet totally clear. The paper takes the form of six theses on various aspects of the ongoing transition to digital libraries. These theses have been presented at a forum on the German "retrodigitization" program. The program aims at the systematic conversion of library resources into digital form, concentrates for a number of reasons on material primarily of interest to the Humanities, and is funded by the German research council. As such this program is directly aimed at improving the overall infrastructure of academic research; other users of libraries are of interest, but are not central to the program.
    Content
    Theses: 1. Who should be addressed by digital libraries? How shall we measure whether we have reached the desired audience? Thesis: The primary audience for a digital library is neither the leading specialist in the respective field, nor the freshman, but the advanced student or young researcher and the "almost specialist". The primary topic of digitization projects should not be the absolute top range of the "treasures" of a collection, but those materials that we always have wanted to promote if they were just marginally more important. Whether we effectively serve them to the appropriate community of serious users can only be measured according to criteria that have yet to be developed. 2. The appropriate size of digital libraries and their access tools Thesis: Digital collections need a critical, minimal size to make their access worthwhile. In the end, users want to access information, not metadata or gimmicks. 3. The quality of digital objects Thesis: If digital library resources are to be integrated into the daily work of the research community, they must appear on the screen of the researcher in a quality that is useful in actual work. 4. The granularity / modularity of digital repositories Thesis: While digital libraries are self-contained bodies of information, they are not the basic unit that most users want to access. Users are, as a rule, more interested in the individual objects in the library and need a straightforward way to access them. 5. Digital collections as integrated reference systems Thesis: Traditional libraries support their collections with reference material. Digital collections need to find appropriate models to replicate this functionality. 6. Library and teaching Thesis: The use of multimedia in teaching is as much of a current buzzword as the creation of digital collections. It is obvious that they should be connected. A clear-cut separation of the two approaches is nevertheless necessary.

    Abstract
    This article describes the journey from the conception of and vision for a modern search-engine-based search environment to its technological realisation. In doing so, it takes up the thread of an earlier article on this subject, this time from a technical viewpoint. As well as presenting the conceptual considerations of the initial stages, this article will principally elucidate the technological aspects of this journey. The starting point for the deliberations about development of an academic search engine was the experience we gained through the generally successful project "Digital Library NRW", in which from 1998 to 2000-with Bielefeld University Library in overall charge-we designed a system model for an Internet-based library portal with an improved academic search environment at its core. At the heart of this system was a metasearch with an availability function, to which we added a user interface integrating all relevant source material for study and research. The deficiencies of this approach were felt soon after the system was launched in June 2001. There were problems with the stability and performance of the database retrieval system, with the integration of full-text documents and Internet pages, and with acceptance by users, because users are increasingly performing the searches themselves using search engines rather than going to the library for help in doing searches. Since a long list of problems are also encountered using commercial search engines for academic use (in particular the retrieval of academic information and long-term availability), the idea was born for a search engine configured specifically for academic use. We also hoped that with one single access point founded on improved search engine technology, we could access the heterogeneous academic resources of subject-based bibliographic databases, catalogues, electronic newspapers, document servers and academic web pages.

    Abstract
    From a quantitative and qualitative point of view the ETH Library is offering its users an extensive choice of information services. In this respect all researchers, all scientists and also all students have access to nearly all relevant information. This is one side of the coin. On the other hand, this broad, but also heterogeneous bundle of information sources has disadvantages, which should not be underestimated: The more information services and information channels you have, the more complex is it to find what you want to get for your scientific work. A portal-like integration of all the different information resources is still missing. The vision, the main goal of the project "Knowledge Portal" is, to develop a central access system in terms of a "single-point-of-access" for all electronic information services. This means, that all these sources - from the library's catalogue and the fulltext inhouse applications to external, licensed sources - should be accessible via one central Web service. Although the primary target group for this vision is the science community of the ETH Zurich, the interested public should also be taken into account, for the library has also a nation-wide responsibility.The general idea to launch a complex project like that comes from a survey the library did one and a half years ago. We asked a defined sample of scientists what they expected to get from their library and one constant answer was, that they wanted to have one point of access to all the electronic library services and besides this, the search processes should be as simple as possible. We accepted this demand as an order to develop a "single-point-of-access" to all electronic services the library provides. The presentation gives an overview about the general idea of the project and describes the current status.

    Abstract
    Welcome to the very first issue of EuropeanaTech Insight, a multimedia publication about research and development within the EuropeanaTech community. EuropeanaTech is a very active community. It spans all of Europe and is made up of technical experts from the various disciplines within digital cultural heritage. At any given moment, members can be found presenting their work in project meetings, seminars and conferences around the world. Now, through EuropeanaTech Insight, we can share that inspiring work with the whole community. In our first three issues, we're showcasing topics discussed at the EuropeanaTech 2015 Conference, an exciting event that gave rise to lots of innovative ideas and fruitful conversations on the themes of data quality, data modelling, open data, data re-use, multilingualism and discovery. Welcome, bienvenue, bienvenido, Välkommen, Tervetuloa to the first Issue of EuropeanaTech Insight. Are we talking your language? No? Well I can guarantee you Europeana is. One of the European Union's great beauties and strengths is its diversity. That diversity is perhaps most evident in the 24 different languages spoken in the EU. Making it possible for all European citizens to easily and seamlessly communicate in their native language with others who do not speak that language is a huge technical undertaking. Translating documents, news, speeches and historical texts was once exclusively done manually. Clearly, that takes a huge amount of time and resources and means that not everything can be translated... However, with the advances in machine and automatic translation, it's becoming more possible to provide instant and pretty accurate translations. Europeana provides access to over 40 million digitised cultural heritage offering content in over 33 languages. But what value does Europeana provide if people can only find results in their native language? None. That's why the EuropeanaTech community is collectively working towards making it more possible for everyone to discover our collections in their native language. In this issue of EuropeanaTech Insight, we hear from community members who are making great strides in machine translation and enrichment tools to help improve not only access to data, but also how we retrieve, browse and understand it.

    Abstract
    The National Science Foundation's (NSF) National Science, Technology, Engineering, and Mathematics Education Digital Library (NSDL) program comprises a set of projects engaged in a collective effort to build a national digital library of high quality science, technology, engineering, and mathematics (STEM) educational materials for students and teachers at all levels, in both formal and informal settings. By providing broad access to a rich, reliable, and authoritative collection of interactive learning and teaching resources and associated services in a digital environment, the NSDL will encourage and sustain continual improvements in the quality of STEM education for all students, and serve as a resource for lifelong learning. Though the program is relatively new, its vision and operational framework have been developed over a number of years through various workshops and planning meetings. The NSDL program held its first formal funding cycle during fiscal year 2000 (FY00), accepting proposals in four tracks: Core Integration System, Collections, Services, and Targeted Research. Twenty-nine awards were made across these tracks in September 2000. Brief descriptions of each FY00 project appeared in an October 2000 D-Lib Magazine article; full abstracts are available from the Awards Section at <http://www.ehr.nsf.gov/ehr/due/programs/nsdl/>. In FY01 the program received one hundred-nine proposals across its four tracks with the number of proposals in the collections, services, and targeted research tracks increasing to one hundred-one from the eighty received in FY00. In September 2001 grants were awarded to support 35 new projects: 1 project in the core integration track, 18 projects in the collections track, 13 in the services track, and 3 in targeted research. Two NSF directorates, the Directorate for Geosciences (GEO) and the Directorate for Mathematical and Physical Sciences (MPS) are both providing significant co-funding on several projects, illustrating the NSDL program's facilitation of the integration of research and education, an important strategic objective of the NSF. Thus far across both fiscal years of the program fifteen projects have enjoyed this joint support. Following is a list of the FY01 awards indicating the official NSF award number (each beginning with DUE), the project title, the grantee institution, and the name of the Principal Investigator (PI). A condensed description of the project is also included. Full abstracts are available from the Awards Section at the NSDL program site at <http://www.ehr.nsf.gov/ehr/due/programs/nsdl/>. (Grants with shared titles are formal collaborations and are grouped together.) The projects are displayed by track and are listed by award number. In addition, six of these projects have explicit relevance and application to K-12 education. Six others clearly have potential for application to the K-12 arena. The NSDL program will have another funding cycle in fiscal year 2002 with the next program solicitation expected to be available in January 2002, and an anticipated deadline for proposals in mid-April 2002.

    Abstract
    Flexible organization of information is one of the key design challenges in any digital library. For the past year, we have been working with members of the National Digital Library Project (NDLP) at the Library of Congress to build an experimental system to organize and store library collections. This is a report on the work. In particular, we describe how a few technical building blocks are used to organize the material in collections, such as the NDLP's, and how these methods fit into a general distributed computing framework. The technical building blocks are part of a framework that evolved as part of the Computer Science Technical Reports Project (CSTR). This framework is described in the paper, "A Framework for Distributed Digital Object Services", by Robert Kahn and Robert Wilensky (1995). The main building blocks are: "digital objects", which are used to manage digital material in a networked environment; "handles", which identify digital objects and other network resources; and "repositories", in which digital objects are stored. These concepts are amplified in "Key Concepts in the Architecture of the Digital Library", by William Y. Arms (1995). In summer 1995, after earlier experimental development, work began on the implementation of a full digital library system based on this framework. In addition to Kahn/Wilensky and Arms, several working papers further elaborate on the design concepts. A paper by Carl Lagoze and David Ely, "Implementation Issues in an Open Architectural Framework for Digital Object Services", delves into some of the repository concepts. The initial repository implementation was based on a paper by Carl Lagoze, Robert McGrath, Ed Overly and Nancy Yeager, "A Design for Inter-Operable Secure Object Stores (ISOS)". Work on the handle system, which began in 1992, is described in a series of papers that can be found on the Handle Home Page. The National Digital Library Program (NDLP) at the Library of Congress is a large scale project to convert historic collections to digital form and make them widely available over the Internet. The program is described in two articles by Caroline R. Arms, "Historical Collections for the National Digital Library". The NDLP itself draws on experience gained through the earlier American Memory Program. Based on this work, we have built a pilot system that demonstrates how digital objects can be used to organize complex materials, such as those found in the NDLP. The pilot was demonstrated to members of the library in July 1996. The pilot system includes the handle system for identifying digital objects, a pilot repository to store them, and two user interfaces: one designed for librarians to manage digital objects in the repository, the other for library patrons to access the materials stored in the repository. Materials from the NDLP's Coolidge Consumerism compilation have been deposited into the pilot repository. They include a variety of photographs and texts, converted to digital form. The pilot demonstrates the use of handles for identifying such material, the use of meta-objects for managing sets of digital objects, and the choice of metadata. We are now implementing an enhanced prototype system for completion in early 1997.
