    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
    Aktuell stehen Bibliotheken im Bereich Katalogmanagement und Erschließung mehrere Verfahren zur Optimierung ihrer Dienstleistungen zur Verfügung'. Häufig wird versucht, die kundenfreundlichen Dienstleistungsmerkmale von Suchmaschinen unter nicht-kommerziellen Bedingungen einzuführen. Dazu zählen: - Vereinfachung von Suchoberflächen - Anreicherung "magerer" bibliothekarischer Inhaltserschließungsdaten durch Digitalisierung von Inhaltsverzeichnissen und/oder Verknüpfung von Titeldaten mit entsprechender Fremdleistung (z.B. UB Konstanz, UB Heidelberg) - Angebot eines Recommending (z. B. UB Karlsruhe) - Einsatz automatischer Indexierungsverfahren (z.B. Vorarlberger Landesbibliothek) - Ranking von Treffern (z.B. UB Bielefeld)

    Enthält u.a. folgende Aussagen aus einzelnen Bibliotheken oder Verbünden: MARC21 als Austauschformat Die Expertengruppe Datenformate des Standardisierungsausschusses hat am 11. April 2005 getagt, dabei wurden die Arbeitspakete aus einem von der Arbeitsstelle für Standardisierung Der Deutschen Bibliothek vorgelegten Projektund Zeitplan in überschaubare Einheiten aufgegliedert. Ziel ist es, das bestehende MARC21 weitgehend zu übernehmen. Sollten nationale Abweichungen von MARC21 dennoch notwendig sein, so müssen diese einheitlich für alle Verbünde gelten. Bibliotheksservicezentrum Baden-Württemberg (BSZ) SWBPIus "Catalogue enrichment", die Anreicherung von Katalogdaten durch ergänzende Materialien, wie z. B. Rezensionen und Inhaltsverzeichnisse, wird als eine der wichtigsten Möglichkeiten diskutiert, die Nutzung von OPACs zu erleichtern und zu verbessern. Ganz im Trend liegt daher die Anwendung SWBplus, in der das BSZ weiterführende Texte zu Titeln in Verbund- und lokalen OPACs auflegt. Nach ca. 2.500 Dokumenten im Jahr 2003 ist der Bestand mittlerweile bei 12.300 angelangt. Mit 6.900 haben dabei die Inhaltsverzeichnisse die Rezensionen anteilsmäßig überholt. Erreicht wurde dies durch die Mitarbeit der Universitätsbibliotheken Konstanz und Heidelberg, die Inhaltsverzeichnisse scannen und an das BSZ liefern. In diese Kooperation werden nun auch die Universitätsbibliothek Mannheim, die Bibliotheken der PH Ludwigsburg und PH Freiburg sowie die Bibliothek des Bundesgerichtshofs in Karlsruhe eintreten. Vorbereitet wird zudem die Zusammenarbeit mit dem Bibliotheksverbund Bayern, so dass Inhaltsverzeichnisse auch aus Bayern in die Datenbank eingebracht und gemeinsam genutzt werden können. Fehlertolerante Suche in OPACs Gemeinsam mit der Bibliothek der Fachhochschule Konstanz und der Firma exorbyte führt das BSZ derzeit einen Test durch, in dem OPAC-Nutzer bei Unsicherheiten hinsichtlich der Schreibweise von Suchbegriffen unterstützt werden. Dazu wurde dem Horizon-WebPac der FH Konstanz die RechercheSoftware Matchmaker vorgeschaltet, die dem Nutzer neben exakten auch näherungsweise Treffer sowie Alternativen zu den Suchbegriffen anbietet. Sucht man dort nun z. B. nach "Pronnstein", so findet man dennoch unter den ersten Treffern die bekannte mathematische Formelsammlung von Ilja Bronstejn. In einer Befragung, die den Test begleitet, fanden ca. 70% der Nutzer den Einsatz dieser Technologie hilfreich und gaben an, auch die Alternativvorschläge zu nutzen. Weitere Informationen stehen unter der Adresse http://cms.bsz-bw.de/cms/entwicki/ftolsuche/ zur Verfügung. Interessenten an einem Einsatz der Software melden sich bitte beim BSZ, das die Einführung koordiniert.
    Die Deutsche Bibliothek Retrieval von Content In dem Projekt wird angestrebt, Verfahren zu entwickeln und einzuführen, die automatisch und ohne intellektuelle Bearbeitung für das Content-Retrieval ausreichend Sucheinstiege bieten. Dabei kann es sich um die Suche nach Inhalten von Volltexten, digitalen Abbildern, Audiofiles, Videofiles etc. von in Der Deutschen Bibliothek archivierten digitalen Ressourcen oder digitalen Surrogaten archivierter analoger Ressourcen (z. B. OCR-Ergebnisse) handeln. Inhalte, die in elektronischer Form vorhanden sind, aber dem InternetBenutzer Der Deutschen Bibliothek bisher nicht oder nur eingeschränkt zur Verfügung stehen, sollen in möglichst großem Umfang und mit möglichst großem Komfort nutzbar gemacht werden. Darüber hinaus sollen Inhalte benutzt werden, die für ein in ILTIS katalogisiertes Objekt beschreibenden Charakter haben, um auf das beschriebene Objekt zu verweisen. Die höchste Priorität liegt dabei auf der Erschließung von Inhalten in Textformaten. In einem ersten Schritt wurde der Volltext aller Zeitschriften, die im Projekt "Exilpresse digital" digitalisiert wurden, für eine erweiterte Suche genutzt. In einem nächsten Schritt soll die PSI-Software für die Volltextindexierung von Abstracts evaluiert werden. MILOS Mit dem Einsatz von MILOS eröffnet sich die Möglichkeit, nicht oder wenig sachlich erschlossene Bestände automatisch mit ergänzenden Inhaltserschließungsinformationen zu versehen, der Schwerpunkt liegt dabei auf der Freitext-Indexierung. Das bereits in einigen Bibliotheken eingesetzte System, das inzwischen von Der Deutschen Bibliothek für Deutschland lizenziert wurde, wurde in eine UNIX-Version überführt und angepasst. Inzwischen wurde nahezu der gesamte Bestand rückwirkend behandelt, die Daten werden im Gesamt-OPAC für die Recherche zur Verfügung stehen. Die in einer XMLStruktur abgelegten Indexeinträge werden dabei vollständig indexiert und zugänglich gemacht. Ein weiterer Entwicklungsschritt wird in dem Einsatz von MILOS im Online-Verfahren liegen.

    Abstract
    Subject searching is the most common but also the most conflictive searching for end user. The aim of this paper is to check how users expressions match subject headings and to prove if knowledge structure used in online catalogs enhances searching effectiveness. A bibliographic revision about difficulties in subject access and proposed methods to improve it is also presented. For the empirical analysis, transaction logs from two university libraries, online catalogs (CISNE and FAMA) were collected. Results show that more than a quarter of user queries are effective due to an alphabetical subject index approach and browsing through hypertextual links. 1. Introduction Since the 1980's, online public access catalogs (OPAC's) have become usual way to access bibliographic information. During the last two decades the technological development has helped to extend their use, making feasible the access for a whole of users that is getting more and more extensive and heterogeneous, and also to incorporate information resources in electronic formats and to interconnect systems. However, technology seems to have developed faster than our knowledge about the tasks where it has been applied and than the evolution of our capacities for adapting to it. The conceptual model of OPAC has been hardly modified recently, and for interacting with them, users still need to combine the same skills and basic knowledge than at the beginning of its introduction (Borgman, 1986, 2000): a) conceptual knowledge to translate the information need into an appropriate query because of a well-designed mental model of the system, b) semantic and syntactic knowledge to be able to implement that query (access fields, searching type, Boolean logic, etc.) and c) basic technical skills in computing. At present many users have the essential technical skills to make use, with more or less expertise, of a computer. This number is substantially reduced when it is referred to the conceptual, semantic and syntactic knowledge that is necessary to achieve a moderately satisfactory search. An added difficulty arises in subject searching, as users should concrete their unknown information needs in terms that the information retrieval system can understand. Many researches have focused an unskilled searchers' difficulties to enter an effective query. The mental models influence, users assumption about characteristics, structure, contents and operation of the system they interact with have been analysed (Dillon, 2000; Dimitroff, 2000). Another issue that implies difficulties is vocabulary: how to find the right terms to implement a query and to modify it as the case may be. Terminology and expressions characteristics used in searching (Bates, 1993), the match between user terms and the subject headings from the catalog (Carlyle, 1989; Drabensttot, 1996; Drabensttot & Vizine-Goetz, 1994), the incidence of spelling errors (Drabensttot and Weller, 1996; Ferl and Millsap, 1996; Walker and Jones, 1987), users problems
