    Abstract
    Das Internet verändert die Rahmenbedingungen des wissenschaftlichen Publikationswesens einschneidend. Wissenschaftliche Dokumente sind zunehmend elektronisch verfügbar und beginnen, die klassischen Wissenschaftsmedien wie Fachbücher und Fachzeitschriften zu verdrängen. Die Implementierung eines elektronischen Publikationsprozesses ist Voraussetzung für die erfolgreiche Verbreitung wissenschaftlicher Dokumente per Internet. Die Umsetzung setzt jedoch die Einhaltung bestimmter Vorgaben und Regularien voraus, sonst drohen Inkompatibilitäten zwischen den Systemen. Im Kontext von Urheberrechtsnovellierung und Open Access-Bewegung erläutert dieser Beitrag technische und rechtliche Rahmenbedingungen von Online-Publikationen und stellt Projekte und Initiativen vor, die sich auf dem Feld des wissenschaftlichen Publikationswesens betätigen. Ausführlich wurden Problembereiche des aktuellen Publikationsprozesses von Abschlussarbeiten im Studiengang Internationales Informationsmanagement an der Universität Hildesheim mit Hilfe von Interviews untersucht. Auf Grundlage der Zustandsanalyse wurde anschließend der elekronische Publikationsprozess modelliert.

    Abstract
    Examines the use of the Z39.50 Information Retrieval protocol for provision of access to its collections. Z39.50 offers a translation of different search engines developed by library systems suppliers and online database hosts. Traces its development and describes its abstraction and metalanguage, and the TCP/IP and OSI layer. It is being further developed in project ONE - OPAC Network in Europe, and European Union Library Plan project which began in Jan 95, of which the British Library is a partner. It aims to link national library catalogues in an open standards and telecommunications network, and to achieve interoperability by use of Z39.50. Describes the project so far, agreements made, and future developments

    Abstract
    User demands to have access to complete and actual information about research may require integration of data from different CRISs. CRISs are rarely homogenous systems and problems of CRISs integration must be addressed from technological point of view. Implementation of CRIS providing access to heterogeneous data distributed among a number of CRISs is described. A few technologies - distributed databases, web services, semantic web are used for distributed CRIS to address different user requirements. Distributed databases serve to implement very efficient integration of homogenous systems, web services - to provide open access to research information, semantic web - to solve problems of integration semantically and structurally heterogeneous data sources and provide intelligent data retrieval interfaces. The problems of data completeness in distributed systems are addressed and CRIS-adequate solution for data completeness is suggested.

    Abstract
    Metasearch - also called parallel search, federated search, broadcast search, and cross-database search - has become commonplace in the information community's vocabulary. All speak to a common theme of searching and retrieving from multiple databases, sources, platforms, protocols, and vendors at the point of the user's request. Metasearch services rely on a variety of approaches including open standards (such as NISO's Z39.50 and SRU/SRW), proprietary programming interfaces, and "screen scraping." However, the absence of widely supported standards, best practices, and tools makes the metasearch environment less efficient for the metasearch provider, the content provider, and ultimately the end-user. To spur the development of widely supported standards and best practices, the National Information Standards Organization (NISO) sponsored a Metasearch Initiative in 2003 to enable: * metasearch service providers to offer more effective and responsive services, * content providers to deliver enhanced content and protect their intellectual property, and * libraries to deliver a simple search (a.k.a. "Google") that covers the breadth of their vetted commercial and free resources. The Access Management Task Group was one of three groups chartered by NISO as part of the Metasearch Initiative. The focus of the group was on gathering requirements for Metasearch authentication and access needs, inventorying existing processes, developing a series of formal use cases describing the access needs, recommending best practices given today's processes, and recommending and pursing changes to current solutions to better support metasearch applications. In September 2005, the group issued their final report and recommendation. This article summarizes the group's work and final recommendation.

    Abstract
    Purpose - To describe the process and results of the business-planning workpackage of The European Library (TEL) project, in which eight national libraries collaborated on a joint approach to access to their digital libraries. Design/methodology/approach - The methodology was in three parts: first, a literature review and the mapping of the partners' existing and planned digital products and services, then a structured interview or survey to determine the partners' business requirements from TEL, then a harmonization process, and finally the results were then combined with normal business planning elements to produce a mission and final business plan. Findings - Business planning for digital libraries has hitherto not been widely reported. The methodology proved to be an effective method of achieving mutual agreement among partners with widely different aims and characteristics. Eleven harmonized service aspirations were agreed and five categories of business aims. Research limitations/implications - Focused on the business aims of national libraries, but the methodology can be relevant to other collaborative projects. Together with the few existing other reports, this can form the basis for a new field of work. Practical implications - The work described led directly to the creation of an operational service, which will be open to all European national libraries. Originality/value - As far as is known, the first reporting of a collaborative international planning process for a digital library, and maybe the first multi-partner business plan between national libraries.

    Abstract
    Proposes a new model for bibliographic access, the virtual catalogue, to serve the virtual library. Suggests the use of current software and networks to build links between bibliographic databases of all kinds, including full text, to enable the user to search a specified subset of databases. Suggests that local data be limited to holdings information linked to, but separate from, bibliographic databases both local and remote

    Footnote
    Rez. in: JASIST 54(2003) no.12, S.1166-1167 (Brenda Chawner): "Kochtanek and Matthews have written a welcome addition to the small set of introductory texts an applications of information technology to library and information Services. The book has fourteen chapters grouped into four sections: "The Broader Context," "The Technologies," "Management Issues," and "Future Considerations." Two chapters provide the broad content, with the first giving a historical overview of the development and adoption of "library information systems." Kochtanek and Matthews define this as "a wide array of solutions that previously might have been considered separate industries with distinctly different marketplaces" (p. 3), referring specifically to integrated library systems (ILS, and offen called library management systems in this part of the world), and online databases, plus the more recent developments of Web-based resources, digital libraries, ebooks, and ejournals. They characterize technology adoption patterns in libraries as ranging from "bleeding edge" to "leading edge" to "in the wedge" to "trailing edge"-this is a catchy restatement of adopter categories from Rogers' diffusion of innovation theory, where they are more conventionally known as "early adopters," "early majority," "late majority," and "laggards." This chapter concludes with a look at more general technology trends that have affected library applications, including developments in hardware (moving from mainframes to minicomputers to personal Computers), changes in software development (from in-house to packages), and developments in communications technology (from dedicated host Computers to more open networks to the current distributed environment found with the Internet). This is followed by a chapter describing the ILS and online database industries in some detail. "The Technologies" begins with a chapter an the structure and functionality of integrated library systems, which also includes a brief discussion of precision versus recall, managing access to internal documents, indexing and searching, and catalogue maintenance. This is followed by a chapter an open systems, which concludes with a useful list of questions to consider to determine an organization's readiness to adopt open source solutions. As one world expect, this section also includes a detailed chapter an telecommunications and networking, which includes types of networks, transmission media, network topologies, switching techniques (ranging from dial up and leased lines to ISDN/DSL, frame relay, and ATM). It concludes with a chapter an the role and importance of standards, which covers the need for standards and standards organizations, and gives examples of different types of standards, such as MARC, Dublin Core, Z39.50, and markup standards such as SGML, HTML, and XML. Unicode is also covered but only briefly. This section world be strengthened by a chapter an hardware concepts-the authors assume that their reader is already familiar with these, which may not be true in all cases (for example, the phrase "client-Server" is first used an page 11, but only given a brief definition in the glossary). Burke's Library Technology Companion: A Basic Guide for Library Staff (New York: Neal-Schuman, 2001) might be useful to fill this gap at an introductory level, and Saffady's Introduction to Automation for Librarians, 4th ed. (Chicago: American Library Association, 1999) world be better for those interested in more detail. The final two sections, however, are the book's real strength, with a strong focus an management issues, and this content distinguishes it from other books an this topic such as Ferguson and Hebels Computers for Librarians: an Introduction to Systems and Applications (Waggawagga, NSW: Centre for Information Studies, Charles Sturt University, 1998). ...

    Abstract
    Information subject gateways provide targeted discovery services for their users, giving access to Web resources selected according to quality and subject coverage criteria. Information gateways recognise that they must collaborate on a wide range of issues relating to content to ensure continued success. This report is informed by discussion of content activities at the 1999 Imesh Workshop. The author considers the implications for subject based gateways of co-operation regarding coverage policy, creation of metadata, and provision of searching and browsing across services. Other possibilities for co-operation include working more closely with information providers, and diclosure of information in joint metadata registries

    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 success of the World Wide Web Shows that we can access, search, and retrieve information from globally distributed databases. lf a database, such as a library catalog, has some sort of Web-based front end, we can type its URL into a Web browser and use its HTML-based forms to search for items in that database. Depending an how well the query conforms to the database content, how the search engine interprets the query, and how the server formats the results into HTML, we might actually find something usable. While the first two issues depend an ourselves and the server, an the Web the latter falls to the mercy of HTML, which we all know as a great destroyer of information because it codes for display but not for content description. When looking at an HTML-formatted display, we must depend an our own interpretation to recognize such entities as author names, titles, and subject identifiers. The Web browser can do nothing but display the information. lf we want some other view of the result, such as sorting the records by date (provided it offers such an option to begin with), the server must do it. This makes poor use of the computing power we have at the desktop (or even laptop), which, unless it involves retrieving more records, could easily do the result Set manipulation that we currently send back to the server. Despite having personal computers wich immense computational power, as far as information retrieval goes, we still essentially use them as dumb terminals.

    Rez. in: KO 31(2004) no.2, S.117-118 (D. Campbell): "This excellent volume offers 22 papers delivered at an IFLA Satellite meeting in Dublin Ohio in 2001. The conference gathered together information and computer scientists to discuss an important and difficult question: in what specific ways can the accumulated skills, theories and traditions of librarianship be mobilized to face the challenges of providing subject access to information in present and future networked information environments? The papers which grapple with this question are organized in a surprisingly deft and coherent way. Many conferences and proceedings have unhappy sessions that contain a hodge-podge of papers that didn't quite fit any other categories. As befits a good classificationist, editor I.C. McIlwaine has kept this problem to a minimum. The papers are organized into eight sessions, which split into two broad categories. The first five sessions deal with subject domains, and the last three deal with subject access tools. The five sessions and thirteen papers that discuss access in different domains appear in order of in creasing intension. The first papers deal with access in multilingual environments, followed by papers an access across multiple vocabularies and across sectors, ending up with studies of domain-specific retrieval (primarily education). Some of the papers offer predictably strong work by scholars engaged in ongoing, long-term research. Gerard Riesthuis offers a clear analysis of the complexities of negotiating non-identical thesauri, particularly in cases where hierarchical structure varies across different languages. Hope Olson and Dennis Ward use Olson's familiar and welcome method of using provocative and unconventional theory to generate meliorative approaches to blas in general subject access schemes. Many papers, an the other hand, deal with specific ongoing projects: Renardus, The High Level Thesaurus Project, The Colorado Digitization Project and The Iter Bibliography for medieval and Renaissance material. Most of these papers display a similar structure: an explanation of the theory and purpose of the project, an account of problems encountered in the implementation, and a discussion of the results, both promising and disappointing, thus far. Of these papers, the account of the Multilanguage Access to Subjects Project in Europe (MACS) deserves special mention. In describing how the project is founded an the principle of the equality of languages, with each subject heading language maintained in its own database, and with no single language used as a pivot for the others, Elisabeth Freyre and Max Naudi offer a particularly vivid example of the way the ethics of librarianship translate into pragmatic contexts and concrete procedures. The three sessions and nine papers devoted to subject access tools split into two kinds: papers that discuss the use of theory and research to generate new tools for a networked environment, and those that discuss the transformation of traditional subject access tools in this environment. In the new tool development area, Mary Burke provides a promising example of the bidirectional approach that is so often necessary: in her case study of user-driven classification of photographs, she user personal construct theory to clarify the practice of classification, while at the same time using practice to test the theory. Carol Bean and Rebecca Green offer an intriguing combination of librarianship and computer science, importing frame representation technique from artificial intelligence to standardize syntagmatic relationships to enhance recall and precision.
    The papers discussing the transformation of traditional tools locate the point of transformation in different places. Some, like the papers an DDC, LCC and UDC, suggest that these schemes can be imported into the networked environment and used as a basis for improving access to networked resources, just as they improve access to physical resources. While many of these papers are intriguing, I suspect that convincing those outside the profession will be difficult. In particular, Edward O'Neill and his colleagues, while offering a fascinating suggestion for preserving the Library of Congress Subject Headings and their associated infrastructure by converting them into a faceted scheme, will have an uphill battle convincing the unconverted that LCSH has a place in the online networked environment. Two papers deserve mention for taking a different approach: both Francis Devadason and Maria Ines Cordeiro suggest that we import concepts and techniques rather than realized schemes. Devadason argues for the creation of a faceted pre-coordinate indexing scheme for Internet resources based an Deep Structure indexing, which originates in Bhattacharyya's Postulate-Based Permuted Subject Indexing and in Ranganathan's chain indexing techniques. Cordeiro takes up the vitally important role of authority control in Web environments, suggesting that the techniques of authority control be expanded to enhance user flexibility. By focusing her argument an the concepts rather than an the existing tools, and by making useful and important distinctions between library and non-library uses of authority control, Cordeiro suggests that librarianship's contribution to networked access has less to do with its tools and infrastructure, and more to do with concepts that need to be boldly reinvented. The excellence of this collection derives in part from the energy, insight and diversity of the papers. Credit also goes to the planning and forethought that went into the conference itself by OCLC, the IFLA Classification and Indexing Section, the IFLA Information Technology Section, and the Program Committee, headed by editor I.C. McIlwaine. This collection avoids many of the problems of conference proceedings, and instead offers the best of such proceedings: detail, diversity, and judicious mixtures of theory and practice. Some of the disadvantages that plague conference proceedings appear here. Busy scholars sometimes interpret the concept of "camera-ready copy" creatively, offering diagrams that could have used some streamlining, and label boxes that cut off the tops or bottoms of letters. The papers are necessarily short, and many of them raise issues that deserve more extensive treatment. The issue of subject access in networked environments is crying out for further synthesis at the conceptual and theoretical level. But no synthesis can afford to ignore the kind of energetic, imaginative and important work that the papers in these proceedings represent."

    Abstract
    This paper proposes the integration of tools to provide unified access to remote and heterogeneous archives, the contents of which can be grouped under the same subject, and which have been integrated to allow the user to navigate and conduct thematic searches. The information sources are locally frequently modified, added to, and removed, therefore attention has been paid to the permanence of their references. Source interoperability is supported at language, protocol and schema levels. The architecture is based on a new common schema of the archives which is defined in new representation and query languages on the basis of an ontology to avoid misunderstanding and ambiguity.
