    Abstract
    One finding of the 2006 OCLC study of College Students' Perceptions of Libraries and Information Resources was that students expressed equal levels of trust in libraries and search engines when it came to meeting their information needs in a way that they felt was authoritative. Seeking to incorporate this insight into our own instructional methodology, Schaffer Library at Union College has attempted to engineer a shift from Google to Google Scholar among our student users by representing Scholar as a viable adjunct to the catalog and to snore traditional electronic resources. By attempting to engage student researchers on their own terms, we have discovered that most of them react enthusiastically to the revelation that the Google they think they know so well is, it turns out, a multifaceted resource that is capable of delivering the sort of scholarly information that will meet with their professors' approval. Specifically, this article focuses on the fact that many Google Scholar searches link hack to our own Web catalog where they identify useful book titles that direct OPAC keyword searches have missed.

    Abstract
    The behavior of academic library users has drastically changed in recent years. Internet search engines have become the preferred tool over the library online public access catalog (OPAC) for finding information. Libraries are losing ground to online search engines. In this paper, two aspects of OPAC use are studied: (1) the current OPAC interface and searching capabilities, and (2) the OPAC bibliographic display. The purpose of the study is to find answers to the following questions: Why is the current OPAC ineffective? What can libraries and librarians do to deliver an OPAC that is as good as search engines to better serve our users? Revitalizing the library OPAC is one of the pressing issues that has to be accomplished.

    "Most Web search engines accept natural language queries, perform some kind of fuzzy matching and produce ranked output, displaying first the documents that are most likely to be relevant. On the other hand, most library online public access catalogs (OPACs) an the Web are still Boolean retrieval systems that perform exact matching, and require users to express their search requests precisely in a Boolean search language and to refine their search statements to improve the search results. It is well-documented that users have difficulty searching Boolean OPACs effectively (e.g. Borgman, 1996; Ensor, 1992; Wallace, 1993). One approach to making OPACs easier to use is to develop a natural language search interface that acts as a middleware between the user's Web browser and the OPAC system. The search interface can accept a natural language query from the user and reformulate it as a series of Boolean search statements that are then submitted to the OPAC. The records retrieved by the OPAC are ranked by the search interface before forwarding them to the user's Web browser. The user, then, does not need to interact directly with the Boolean OPAC but with the natural language search interface or search intermediary. The search interface interacts with the OPAC system an the user's behalf. The advantage of this approach is that no modification to the OPAC or library system is required. Furthermore, the search interface can access multiple OPACs, acting as a meta search engine, and integrate search results from various OPACs before sending them to the user. The search interface needs to incorporate a method for converting the user's natural language query into a series of Boolean search statements, and for ranking the OPAC records retrieved. The purpose of this study was to develop a relevancyranking algorithm for a search interface to Boolean OPAC systems. This is part of an on-going effort to develop a knowledge-based search interface to OPACs called the E-Referencer (Khoo et al., 1998, 1999; Poo et al., 2000). E-Referencer v. 2 that has been implemented applies a repertoire of initial search strategies and reformulation strategies to retrieve records from OPACs using the Z39.50 protocol, and also assists users in mapping query keywords to the Library of Congress subject headings."

    Abstract
    Some Online Public Access Catalogues offer a ranking component. However, ranking there is merely text-based and is doomed to fail due to limited text in bibliographic data. The main assumption for the talk is that we are in a situation where the appropriate ranking factors for OPACs should be defined, while the implementation is no major problem. We must define what we want, and not so much focus on the technical work. Some deep thinking is necessary on the "perfect results set" and how we can achieve it through ranking. The talk presents a set of potential ranking factors and clustering possibilities for further discussion. A look at commercial Web search engines could provide us with ideas how ranking can be improved with additional factors. Search engines are way beyond pure text-based ranking and apply ranking factors in the groups like popularity, freshness, personalisation, etc. The talk describes the main factors used in search engines and how derivatives of these could be used for libraries' purposes. The goal of ranking is to provide the user with the best-suitable results on top of the results list. How can this goal be achieved with the library catalogue and also concerning the library's different collections and databases? The assumption is that ranking of such materials is a complex problem and is yet nowhere near solved. Libraries should focus on ranking to improve user experience.

    Abstract
    Die verschiedenen unter dem Schlagwort "Bibliothek 2.0" zusammengefassten neuen Dienste und Komponenten wie etwa Wikis, Tagging-Systeme und Blogs sind seit einiger Zeit in aller Munde und dringen über Fortbildungsveranstaltungen, Konferenzen und Publikationsorgane immer mehr in das deutschsprachige Bibliothekswesen ein. Darüber hinaus gibt es öffentlich geförderte Projekte zu bibliothekarischen 2.0-Themen und sogar ein Projekt, welches sich explizit einen 2.0-Katalog zum Ziel gesetzt hat. In diesem Beitrag soll es nun nicht um die Vorstellung eines weiteren Projekts im Dienste des Themas "Bibliothek 2.0" gehen, ebenso hat dieser Beitrag nicht den Anspruch, die Diskussion über die möglichen Vor- oder Nachteile dieser Thematik auf theoretischer Ebene voranzubringen. Vielmehr wird hier ganz praktisch aus Sicht einer kleinen Universitätsbibliothek, der Bibliothek der Helmut-SchmidtUniversität (HSU) - Universität der Bundeswehr Hamburg, aufgezeigt, wie das Thema "Web/Bibliothek 2.0" durchaus neben und in Unterstützung von weiteren nutzerorientierten Servicedienstleistungen auch in kleinen Schritten positive Auswirkungen für die Nutzerinnen und Nutzer haben kann. Der Focus wird dabei auf dem zentralen Arbeits- und Rechercheinstrument der Bibliotheksnutzer liegen, dem Bibliothekskatalog. Speziell wird es darum gehen, wie auf relativ einfache Art und Weise durch Anwendung verschiedener Elemente anderer Dienste und Anbieter sowie das Aufgreifen von Schnittstellen und wenig aufwendigen Verbesserungen, Mehrwert für die Nutzerinnen und Nutzer zu erzielen ist. Ein zentraler Begriff bei fast allen Überlegungen, die im Zusammenhang mit der Verbesserung und Anreicherung des Kataloges stehen, war und ist das Thema "Mash-up". Unter Mashups - ein Begriff, der gerade im Zusammenhang mit dem Thema "Web 2.0" im deutschsprachigen Raum eingeführt und adaptiert wurde - wird das Verfahren bezeichnet, Web-Inhalte neu zu kombinieren. Dabei nutzt man bei und für Mashups offene "APIs" (Application Programming Interfaces, also offene Programmierschnittstellen), die von anderen Web-Anwendungen zur Verfügung gestellt werden.

    Abstract
    Today's information seekers have been conditioned by Web search engines to expect immediate gratification as the result of user-friendly Web experiences. In contrast, it is increasingly apparent that traditional library OPACs do not provide the same ease of use or access to information. National Bibliographic Agencies (NBAs) and libraries everywhere need to respond to this discrepancy by initiating measures to enrich their databases and bibliographic products with much more information than is currently captured in records for resources. At the same time, NBAs must address the need for a new generation of OPACs that offers significantly enhanced functionality, much of which can be based on standard features of Web search engines and online bookstores. In view of alternatives available to information seekers, these needs require immediate attention if NBAs and libraries are to retain the support of satisfied users into the 21 st century. This paper offers specific recommendations to assist them in identifying and implementing appropriate responses.

    Abstract
    Thirty-one patrons, who were selected by Slone to provide a range of age and experience, agreed when approached while using the catalog of the Wake County library system to try searching via the Internet. Fifteen searched the Wake County online catalog in this manner and 16 searched the World Wide Web, including that catalog. They were subjected to brief pre-structured taped interviews before and after their searches and observed during the searching process resulting in a log of behaviors, comments, pages accessed, and time spent. Data were analyzed across participants and categories. Web searches were characterized as linking, URL, search engine, within a site domain, and searching a web catalog; and participants by the number of these techniques used. Four used only one, 13 used two, 11 used three, two used four, and one all five. Participant experience was characterized as never used, used search engines, browsing experience, email experience, URL experience, catalog experience, and finally chat room/newsgroup experience. Sixteen percent of the participants had never used the Internet, 71% had used search engines, 65% had browsed, 58% had used email, 39% had used URLs, 39% had used online catalogs, and 32% had used chat rooms. The catalog was normally consulted before the web, where both were used, and experience with an online catalog assists in web use. Scrolling was found to be unpopular and practiced halfheartedly.

    Abstract
    Due to the advances in information retrieval in the past decades, search engines have become extremely efficient at acquiring useful sources in response to a user's query. However, for more prolonged and complex information seeking tasks, these search engines are not as well suited. During complex information seeking tasks, various stages may occur, which imply varying support needs for users. However, the implications of theoretical information seeking models for concrete search user interfaces (SUI) design are unclear, both at the level of the individual features and of the whole interface. Guidelines and design patterns for concrete SUIs, on the other hand, provide recommendations for feature design, but these are separated from their role in the information seeking process. This chapter addresses the question of how to design SUIs with enhanced support for the macro-level process, first by reviewing previous research. Subsequently, we outline a framework for complex task support, which explicitly connects the temporal development of complex tasks with different levels of support by SUI features. This is followed by a discussion of concrete system examples which include elements of the three dimensions of our framework in an exploratory search and sensemaking context. Moreover, we discuss the connection of navigation with the search-oriented framework. In our final discussion and conclusion, we provide recommendations for designing more holistic SUIs which potentially evolve along with a user's information seeking process.

    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
    The starting-point of the paper is the debate recently developed in LIS literature about OPAC enhancement and the necessity to design OPACs based on search engines features. Supposed improving tools as relevance ranking and relevance feedback devices are examinated. Possible OPAC development lines, based on theoretical examination of relevance and pertinence concepts, according to Sarácevic view, and following semantics perspectives, are presented. Finally, enhancement of OPACs starting from their inner characteristics is proposed, and a plan to improve semantic search functions while maintaining existing indexing methodologies, that is document conceptual analysis, is outlined.

    Abstract
    In one form or another, from a mental list in the mind of the librarian, to book catalogs, card indexes, and online information retrieval systems, some type of meta access has existed to guide library users through library collections. Over the last 40 years, these constructs of paper and wood evolved into Online Public Access Catalogs (OPACs). When the catalog shifted out of drawers and off of three by five cards to become a networked, universally accessible entity, its role in the library shifted as well. The OPAC competes with the World Wide Web, metadata registries, search engines, and more sophisticated database structures for attention. Amongst this assortment of access mechanisms, the purpose of the OPAC has become muddled. The OPAC has now become one information source among many and one of a number of portals for accessing library collections and beyond.

    Abstract
    Purpose - Library online public access catalogues (OPACs) are considered to be unattractive in comparison with popular internet sites. In 2000, the authors presented some suggestions on how library catalogues should change. Have librarians actually made their OPACs more user-friendly by adopting techniques and technologies already present in other information resources? This paper aims to address these issues. Design/methodology/approach - The characteristics of four OPACs, one online bookstore and two internet search engines are analyzed. The paper reviews some of the changes and directions suggested by researchers and adds some of authors own. All this is in the hope that library catalogues will survive "Google attack." Findings - Changes are identified in the information services studied over a seven-year period. Least development is found in library catalogues. Suggestions are made for library catalogues of the future. Research limitations/implications - A library catalogue, a web search engine and an internet bookstore cannot be compared directly because of differences in scope. But features from each could be fruitfully used in others. Practical implications - OPACs must be both attractive and useful. They should be at least as easy to use as their competitors. With the results of research as well as the knowledge librarians have many years, the profession should be able to develop better OPACs than we have today and regain lost ground in the "competition" for those with information needs. Originality/value - A comparison of OPAC features in 2000 and 2007, even if subjective, can provide a panoramic view of the development of the field.

    Content
    "MOST INTEGRATED library systems, as they are currently configured and used, should be removed from public view. Before I say why, let me be clean that I think the integrated library system serves a very important, albeit limited, role. An integrated library system should serve as a key piece of the infrastructure of a library, handling such tasks as ma terials acquisition, cataloging (including holdings, of course), and circulation. The integrated library system should be a complete and accurate recording of a local library's holdings. It should not be presented to users as the primary system for locating information. It fails badly at that important job. - Lack of content- The central problem of almost any library catalog system is that it typically includes only information about the books and journals held by a parficular library. Most do not provide access to joumal article indexes, web search engines, or even selective web directories like the Librarians' Index to the Internet. If they do offen such access, it is only via links to these services. The library catalog is far from onestop shopping for information. Although we acknowledge that fact to each other, we still treat it as if it were the best place in the universe to begin a search. Most of us give the catalog a place of great prominente an our web pages. But Information for each book is limited to the author, title, and a few subject headings. Seldom can book reviews, jacket summaries, recommendations, or tables of contents be found-or anything at all to help users determine if they want the material. - Lack of coverage - Most catalogs do not allow patrons to discover even all the books that are available to them. If you're lucky, your catalog may cover the collections of those libraries with which you have close ties-such as a regional network. But that leaves out all those items that could be requested via interlibrary loan. As Steve Coffman pointed out in his "Building Earth's Largest Library" article, we must show our users the universe that is open to them, highlight the items most accessible, and provide an estimate of how long it would take to obtain other items. - Inability to increase coverage - Despite some well-meaning attempts to smash everything of interest into the library catalog, the fact remains that most integrated library systems expect MARC records and MARC records only. This means that whatever we want to put into the catalog must be described using MARC and AACR2 (see "Marc Must Die," LJ 10/15/02, p. 26ff.). This is a barrier to dramatically increasing the scope of a catalog system, even if we decided to do it. How would you, for example, use the Open Archives Initiative Harvesting Protocol to crawl the bibliographic records of remote repositories and make them searchable within your library catalog? It can't be dope, and it shouldn't. The library catalog should be a record of a given library's holdings. Period.
    - User Interface hostility - Recently I used the Library catalogs of two public libraries, new products from two major library vendors. A link an one catalog said "Knowledge Portal," whatever that was supposed to mean. Clicking an it brought you to two choices: Z39.50 Bibliographic Sites and the World Wide Web. No public library user will have the faintest clue what Z39.50 is. The other catalog launched a Java applet that before long froze my web browser so badly I was forced to shut the program down. Pick a popular book and pretend you are a library patron. Choose three to five libraries at random from the lib web-cats site (pick catalogs that are not using your system) and attempt to find your book. Try as much as possible to see the system through the eyes of your patrons-a teenager, a retiree, or an older faculty member. You may not always like what you see. Now go back to your own system and try the same thing. - What should the public see? - Our users deserve an information system that helps them find all different kinds of resources-books, articles, web pages, working papers in institutional repositories-and gives them the tools to focus in an what they want. This is not, and should not be, the library catalog. It must communicate with the catalog, but it will also need to interface with other information systems, such as vendor databases and web search engines. What will such a tool look like? We are seeing the beginnings of such a tool in the current offerings of cross-database search tools from a few vendors (see "Cross-Database Search," LJ 10/15/01, p. 29ff). We are in the early stages of developing the kind of robust, userfriendly tool that will be required before we can pull our catalogs from public view. Meanwhile, we can begin by making what we have easier to understand and use."

    Abstract
    Purpose - The paper aims to describe a proof of concept web application designed to allow users to search for library materials with geographic subject headings using Google Maps as the primary interface for navigation. The purpose of the paper is to describe the development of an innovative tool that one library has created to provide users with a new way to access bibliographic records. Design/methodology/approach - The approach taken is descriptive, with the development process for the proof of concept laid out in detail and placed it within the broader contexts of web application development at the host library and the emergence of Web 2.0 tools. Findings - The paper shows that unique and valuable new methods of accessing bibliographic data can be created through the use of application programming interfaces (APIs), one of the more powerful tools available to web application developers today. Research limitations/implications - Challenges of working with geographic information in subject headings of bibliographic records are discussed, and potential methods for dealing with these challenges are described. Originality/value - The paper shows that it is possible to use APIs provided by large internet entities such as Google to create map based navigational tools for accessing bibliographic information. It also shows the value of allowing library systems staff to explore new technologies.
