    Abstract
    Subject access to monographs through online public access catalogs (OPACs) has always been a major concern for large research and/or academic libraries. Academic library practice of providing subject access to monographs has proven inadequate, especially in the case of composite works. Many techniques have been proposed to enhance subject treatment of monographs in OPACs. This article briefly reviews these efforts in the past and presents the case of adding Tables of Contents as one of the Most useful and probably also one of the Most costeffective ways of improving subject access to Monographs in an academic environment.

    Abstract
    Die Kombination von gleichzeitig mehreren oder vielen intellektuell konstruierten Thesauri und maschineller Indexierung der Texte führt zu einer umfassenderen und spezifischeren Beschreibung von Dokumenten als die intellektuelle Klassifizierung oder die Indexierung allein. Durch die Expansion der Suchfrage um Thesauruseinträge wird der recall deutlich erhöht. Zugleich kann die intellektuelle Klassifizierung in überschaubaren Domänen dazu genutzt werden, baumartig in Dokumentenkollektionen zu navigieren oder die Suche erst in Teilbereichen der Klassifikation zu beginnen, um die precision zu erhöhen. Der Einsatz von Thesauruskollektionen wird an den Beispielen dandelon.com, Landtagsinformationssystem Vorarlberg und der Landeshomepage vorarlberg.at dargestellt.

    Abstract
    As librarians plan ahead to make subject enhancements available to online searchers in various possible file locations and formats, they may want to base their decisions on implications for online searching. This paper explores some of these implications with respect to unique and misleading terminology in tables of contents, Choice abstracts, and reviews from Computing reviews for thirty-six books on information and computer science chosen from the 1987 issues of Choice. It also discusses possible interacting functions in the search process served by these subject enhancements, assigned LCSH, and book title terminology

    Abstract
    Vom verflixten siebten Jahr kann man in Bregenz bisher nicht sprechen, im Gegenteil: Die Vorarlberger Landesbibliothek (VLB) hat kurz vor Ostern 2008 ihr 100.000. Inhaltsverzeichnis mit intelligentCAPTURE gescannt. Damit ist der Katalogeintrag von etwa 70 Prozent des betroffenen Freihandbestandes und sämtlicher Neuzugänge ab 2002 zusätzlich mit dem Inhaltsverzeichnis und zum Teil mit der Abbildung des Buchdeckels versehen. Die derzeitige Durchsatzrate beträgt pro Jahr 30.000 bibliographische Einheiten bei einem Personaleinsatz von 40 Stunden pro Woche. Die vollständige Erschließung des Buchbestandes in der Freihandaufstellung ist in Reichweite; ganz ohne Fördermittel im laufenden Betrieb; eine schlanke Lösung sowohl organisatorisch als auch finanziell. Da im Rahmen der Zusammenarbeit mit dandelon.com inzwischen weitere Bibliotheken in einem elegant gelösten Arbeitsablauf kooperativ erschließen, können wir bei Neuerscheinungen bereits die Hälfte als Fremddaten übernehmen. Die VLB hat mit der Digitalisierung, OCR-Konvertierung und maschinellen Indexierung von Inhaltsverzeichnissen und dem mehrsprachigen, semantischen Retrieval in der Suchmaschine dandelon.com zusammen mit der Firma AGI. Information Management Consultants Impulse im Bibliothekswesen gesetzt. Wer 2002 noch bezweifelte, dass dieser Ansatz erfolgreich sein wurde, wurde inzwischen eines Besseren belehrt. Zu offensichtlich ist der Mehrwert, den allein die Moglichkeit der entscheidend verbesserten Relevanzbeurteilung uber den OPAC bietet (http://vlb-katalog.vorarlberg.de). Er erfordert von einer zeitgemasen Bibliothek geradezu das Angebot solcher Zusatzinformationen. Aber die Anreicherung mit den Angaben aus den Inhaltsverzeichnissen bieten weit mehr, denn es entsteht durch die maschinelle Indexierung eine vollig neue Dimension an Retrievalmoglichkeiten. Die vollständige Erfassung unseres Bestandes war immer erklärtes Ziel unseres Projektes, weil wir gesehen haben, dass wir den Nutzern dadurch einen erheblichen Zusatznutzen bieten können, der in einem unbeschreiblich günstigen Verhältnis zum personellen und finanziellen Einsatz steht. Damit, dass wir dieses Ziel so schnell erreichen könnten, hatten wir nicht gerechnet.

    Abstract
    Subject access plays an important part when plans are made for an on-line public access catalogue (OPAC). Therefore, current subject searching facilities in OPACs should be accessed carefully. These facilities include, amongst other things, phrase searching, keyword searching and class number retrieval. Users reaction have been instrumental in identifying certain shortcomings in subject access to OPACs. Points out certain shortcomings in subject access, as shown by a number of research projects undertaken during the past decade. Highlights aspects which could, in future, improve subject access in OPACs. This could be achieved by either enhancing content representation in the records within the OPAC data base or by enhancing the searchability and browsability of the OPAC. Considers whether the on-line catalogue will ever be a finished, perfect product, or achieve the universal, familiar uniformity experienced by users of the 20th century card catalogue.

    Abstract
    Myriad new information resources are available to contemporary library users. While print remains the foundation of most collections, libraries are also beginning to provide access to an array of bibliographic, numeric, and full-text databases. As more and more information is produced in electronic form and presented at computer workstations, the library catalog is being given an expanded role. The expanded catalog will play a crucial part in organizing information in electronic libraries, and in providing navigational assistance to library users. Like the traditional card catalog, the expanded catalog will not only lead to specific items or groups of sources, but also will provide connections to related materials. These connections will uses standard data elements to link the results of a search in one database with related material in another. For example, links will show local library holdings of sources in citation databases. Cornell University's Mann Library serves the College of Agriculture and Life Sciences, the College of Human Ecology, and the Division of Biological Sciences. As part of electronic library development, Mann staff have been analyzing issues involved in making it possible for Agricola and BIOSIS users to see, automatically, which of their retrieved citations are from sources available in the Cornell libraries. Samples of citations from Agricola and BIOSIS were drawn, and data elements present in these records were compared with bibliographic records of the library's holdings. In some cases, links would be provided by ISSNs. The study shows, however, that the presence of standard identifiers such as ISSN, USBN, or CODEN cannot be assumed, and other linking algorithms must be developed. This article presents study results, provides an overview of several linking systems, and identifies some of the difficulties caused by lack of standardization between different bibliographic databases. It is clear that the concept of an expanded catalog will require not only links between information resources but agreements among information professionals on standard data elements.

    Abstract
    This report describes an experiment in subject enhancement conducted at an academic research library. Subjects and contents notes were added to online catalog records for a group of previously uncirculated social science essay collections, and circulation was monitored over one academic year. A control group, plus a third group with added contents notes but no extra subjects, were also monitored. Results showed an improvement in recorded use for the subject-enhanced titles, but not for titles that only had added contents notes. The effects of browsing, keyword searching, and OPAC display are discussed

    Abstract
    This article describes our efforts in supporting information retrieval from OCR degraded text. In particular, we report our approach to an automatic cataloging and searching contest for books in multiple languages. In this contest, 500 books in English, German, French, and Italian published during the 1770s to 1970s are scanned into images and OCRed to digital text. The goal is to use only automatic ways to extract information for sophisticated searching. We adopted the vector space retrieval model, an n-gram indexing method, and a special weighting scheme to tackle this problem. Although the performance by this approach is slightly inferior to the best approach, which is mainly based on regular expression match, one advantage of our approach is that it is less language dependent and less layout sensitive, thus is readily applicable to other languages and document collections. Problems of OCR text retrieval for some Asian languages are also discussed in this article, and solutions are suggested

    Abstract
    Kurz nach 11 Uhr erscheint ein seltsamer Mensch am InfoDesk der Universitätsbibliothek und spricht die diensthabende Bibliothekarin an: "Frosch!". Mh, was meint der? Sonst sagt er nichts. Will er sich vorstellen? Herr Frosch? Wurde er im Eingangsbereich von einem Frosch erschreckt, der sich zufällig dorthin verirrte? Sucht er Literatur zu Fröschen? Märchen, mit dem Froschkönig? Will er Froschschenkel zum Mittagessen zubereiten? Ein Erstsemester, der in Biologie sich mit dem Tier befasst? Frosch als Fresser oder als gefressen werden? Ist das etwa der Autor Karl Frosch oder sucht er Literatur von diesem? Ein der Sprache nicht ganz mächtiger Ausländer? Ein Verrückter? Mh, Alter, Geschlecht, Kleidung, Sprache, Gestik - all dies wird schnell durchgeprüft. Ganz so kurz, kann man doch eine Dipl.-Bibl. nicht so einfach ansprechen. Unverschämt! ... Ungewöhnlich? Keineswegs, ist dies doch unsere normale Art, sich mit Suchmaschinen und OPACs zu unterhalten. Ebenso wenig wie eine Bibliothekarin hier eine zufriedenstellende Antwort bieten kann, weiß auch keine Suchmaschine, was das Anliegen dieser Person ist. Weit schneller als die Bibliothekarin kann sie aber in ihrem Index das Suchwort aufspüren und eine Treffermenge vermelden. Der Schlitz der Suchmaschine hat im Gegensatz zum "Schlitz" der Bibliothek, dem InfoDesk, keine Augen und Ohren, hat kein stimulierendes Lächeln, die Frage weiter erläutern zu lassen.

    Abstract
    Quantitativer Umfang des Bestandes Dass die Bayerische Staatsbibliothek München (BSB) eine bedeutende Sammlung an Handschriften besitzt und die an Exemplaren reichste Inkunabelsammlung aufzuweisen hat, ist allgemein bekannt. Demgegenüber weit weniger bekannt dürfte die Tatsache sein, dass dort auch umfangreiche Bestände anderer Bibliotheken auf Mikrofilm bzw. Mikrofiche vorhanden sind, die in den vergangenen Jahrzehnten von Firmen wie World Microfilm Publications kommerziell vertrieben und von der BSB erworben wurden. Dabei handelt es sich - grob geschätzt - um 6.000 Handschriften (ohne Musikhandschriften) und über 5.000 Inkunabeln auf insgesamt ca. 1.850 Filmrollen und knapp 25.000 Mikrofiches. Listenartige Erfassungsmöglichkeiten Die frühesten Erwerbungen wurden in der Handschriftenabteilung im Freihandmagazin aufgestellt; ein Nachweis im Katalog war seinerzeit nicht erfolgt. Der größere - katalogisierte - Teil befand sich hingegen, räumlich getrennt, im allgemeinen Magazin; dieser wurde nach und nach in die Handbibliothek der Handschriftenabteilung (Hbh) verbracht und - zusammen mit den bereits in der Abteilung befindlichen Filmen - mit entsprechenden Signaturen versehen. Am Ende stand der katalogmäßige Nachweis der gesamten Mikroformen. Aufgrund der ursprünglich disparaten Aufstellung und unterschiedlichen Erschließung war es teilweise recht schwierig gewesen, die entsprechenden Verfilmungen (zumal Sammlungen) ausfindig zu machen. Auf der Basis einer bereits vorhandenen Liste wurde daher ein "Verzeichnis der Mikrofilmsammlungen in der Handschriftenabteilung der BSB" analog den Verzeichnissen der Mikroformen zur Geschichte bzw. zur Musikwissenschaft ins Netz gestellt. Unter der Adresse http://www.bsb-muenchen.de/mikro/hand.htm kann man sich einen nach Provenienzen geordneten Überblick über diese wichtigen, bis dato aber zu wenig genutzten Bestände verschaffen.
    Besonders interessant dürften dabei sicherlich die Verfilmungen von mittelalterlichen und frühneuzeitlichen theologischen, juristischen, literarischen und naturwissenschaftlichen Handschriften aus britischen Bibliotheken sein. Illuminierte Handschriften liegen häufig auf Farbmikrofilm vor. Sie stammen nicht nur aus der British Library, sondern auch aus zahlreichen Bibliotheken von Colleges der Universitäten Oxford und Cambridge. Außerdem gibt es eine Komplettverfilmung der orientalischen Handschriften der School of Oriental and African Studies in London. Neben den als Mikroform verfügbaren Handschriften beinhaltet die Liste auch die Fiche-Sammlung "lncunabula", in der nach thematischen Gesichtspunkten (Bibeln, italienische Drucke, Medizin, usw.) zusammengefasst Drucke bis 1500 aus Bibliotheken der ganzen Welt präsentiert werden, darunter auch aus der BSB. Des weiteren führt das Verzeichnis mikroverfilmte Findmittel auf, wobei der "Cranz" (ein Führer zu veröffentlichten und die Verfilmung unveröffentlichter Handschriftenverzeichnisse auf insgesamt 386 Filmrollen) und die Verfilmung von Inventaren der Handschriftenbestände der Bibliothèque nationale de France (ca. 2.500 Mikrofiches) besonders erwähnenswert sind.

    Abstract
    Ein weiterer Meilenstein beim Catalogue Enrichment ist die Kooperation zwischen dem Hochschulbibliothekszentrum NRW (hbz) und Springer Science+Business Media. Ziel der Kooperation ist eine Anreicherung der im hbz-Verbundbestand nachgewiesenen Springer-Titel um Inhalte wie Buchcover, Inhaltsverzeichnisse, Vorworte und Probekapitel.
    Content
    "»Die Anreicherung von Bibliothekskatalogen bedeutet zusätzliche Informationen für die Bibliotheksnutzer«, betont Hans Ollig; der Leiter des hbz. »Sie erhalten dadurch wichtige Orientierungs- und Entscheidungshilfen bei der Auswahl der Literatur.« Der Springer-Verlag lieferte dem hbz zunächst einen Grundbestand von 22.000 Objekten der Verlagsproduktion der letzten fünf Jahre. Daran schließen sich Ergänzungslieferungen an: Neue Titel des Verlags werden monatlich auf den Servern des hbz eingespielt. Technische Basis des Catalogue Enrichment sind das Verbundsystem Aleph, der hbz-Medienserver und die hbz-Suchmaschinentechnologie zur Präsentation der Daten. Zunächst sind die rund 17.000 im hbz-Verbundkatalog vorhandenen Springer-Titel in den Medienserver geladen und in der hbz-Verbunddatenbank verfügbar gemacht worden. Von dort aus werden sie in die lokalen Kataloge der Verbundbibliotheken und in den Dreiländerkatalog des hbz integriert. Die Daten werden soweit möglich volltextlich indexiert und können somit bei der Recherche direkt durchsucht werden. Die Kooperation mit Springer Science+Business Media ist erst der Anfang: Das hbz verhandelt bereits mit weiteren Verlagen und Datenanbietern über Kooperationen, um den Bibliotheken weiteren, über die traditionelle sachliche Erschließung hinausgehenden Mehrwert für ihre Kataloge bieten zu können,"

    Abstract
    Angesichts der Allgegenwart von Amazon und Google sowie von zunehmend verwöhnten Internetnutzern sind die Bibliotheken gefordert, das Feld der Innovation nicht allein kommerziellen Anbietern zu überlassen. Das hbz hat in einer Kooperation mit der USB Köln und der ZB MED ein erfolgreiches Projekt zum Catalogue Enrichment gestartet, das in diesem Umfang in Deutschland bisher einmalig ist und für weitere Vorhaben richtungsweisend sein könnte.

    Abstract
    Contents enhancement of catalog records may increase access to books in collections and aid in effective resource sharing by providing more detailed descriptions about library holdings in the catalog. A sample of monographs in San Diego State Univ. Library was studied to determine the extent to which information in books from parts of the collection could be represented better by content notes, and to determine how much of this information has subject or analytical applications. The study revealed that approximately 23% of the books contain discrete content information not already represented in catalog records that could be added. Of those, 52% would be citation-based enhancements and 48% would be subject-based. Nearly 65% would require fewer than 25 enhancements, with an average of 8.03 enhancements per book for the total population

    Abstract
    This study examines users' needs for bibliographic enhancement data (BIBED) in academic library catalogs. Qualitative data were collected through 30 academic users' activity logs and follow-up interviews. These 30 participants were recruited from a public university in the United States that has over 19,000 students enrolled and over 600 full-time faculty members. This study identified 19 types of BIBED useful for supporting the five user tasks proposed in the IFLA Library Reference Model and in seven other contexts, such as enhancing one's understanding, offering search instructions, and providing readers' advisory. Findings suggest that adopting BIBFRAME and Semantic Web technologies may enable academic library catalogs to provide BIBED to better meet user needs in various contexts.
