Abstract

In den letzten Jahren ist das Angebot an Academic Search Engines für die Recherche nach Fachliteratur zu allen Wissenschaftsgebieten stark angewachsen und ergänzt die beliebten kommerziellen Angebote wie Web of Science oder Scopus. Der Artikel zeigt die wesentlichen Unterschiede zwischen bibliothekarischen Discovery-Systemen und Academic Search Engines wie Base, Dimensions oder Open Alex auf und diskutiert Möglichkeiten, wie beide von einander profitieren können. Diese Entwicklungsperspektiven betreffen Aspekte wie die Kontextualisierung von Wissen, die Datenmodellierung, die automatischen Datenanreicherung sowie den Zuschnitt von Suchräumen.

Abstract

Discusses the frustrations and challenges of compiling bibliographies that include WWW references. Search and retrieval skills acquired using older online sources are not always transferable to the Web, and evaluation and authentication of resources remain poor. Cited references frequently disappear, leading to complaints from bibliography users. The Web has also changed many users' perceptions of what they should get from other information providers, increasing their expectations and demands, particularly for the more frequent updating of bibliographies. Suggests a partnership approach can help, where users feed back information about the availability of resources they are seeking; this can have many benefits for both parties

Abstract

This article describes the Online Computer Library Center's (OCLC) Open WorldCat program. WorldCat is a worldwide union catalog created and maintained collectively by more than 9,000 member institutions. Open WorldCat seeks to make library collections and services visible and available through popular search engines such as Yahoo! and Google and other heavily used sites on the open Web. In this capacity, Open WorldCat provides an important central connection between the shared information of the library network and the Web. The article describes the history and rationale of the project; explains how Open WorldCat works for information seekers, participating libraries, and partners; and reports on what OCLC has learned from the program to date.

Abstract

Das in dieser Zeitschrift bereits vorgestellte Multisuchsystem E-Connect hat mittlerweile einige äußere und innere Anderungen und Erweiterungen erfahren. Abbildung 1 zeigt das Suchformular für die Suche in mehreren allgemeinen Aufsatz- und Verlagsdatenbanken. Ein entsprechendes Suchformular für die Suche nach Zeitschriftenaufsätzen mehrerer bzw. einzelner Fachgebiete ist ähnlich aufgebaut und enthält u. a. den vereinfachten Zugang zu dem fachlich den gesamten STIVI-Bereich umfassenden EnergyPortal Search und zu weiteren Datenbanken von elektronischen Aufsätzen, Reports und Preprints. Von der Startseite aus kann man jetzt auch über eine Suchmaschine sowohl die im Multisuchsystem als auch die in den Bibliographischen Datenbanken im Internet enthaltenen etwa 160 Datenbanken suchen und anwählen. Damit ist eine Art von digitaler Bibliothek entstanden, die vor allem elektronisch verfügbare Dokumente erschließt

Abstract

More and more libraries are providing access to Web resources through OCLC's (Online Computer Resource Center) Cooperative Online Resource Catalog (CORC) and, by extension, OCLC's WorldCat database. The ability to use a database to its maximum potential depends upon understanding what a database contains and the guidelines for its construction. This study examines the characteristics of Web resources in CORC in terms of their subject matter, the source of the content, publication patterns, and the units of information chosen for representation in the database. The majority of the 414 resources in the sample belonged to the social sciences. Academic libraries and government agencies contributed more than 90% of the records for resources in the sample. Using the Anglo-American Cataloguing Rules, 2d edition (AACR2) definitions for publication patterns that are part of the upcoming 2002 amendments reveals that nearly half of the sample fell into the category of integrating resources. Identifying units of representation of the resources described was more difficult. Existing definitions for Web units in development are not adequate to describe all of the resources in the sample. In addition, there is wide variability in the units of representation chosen for inclusion by the libraries contributing records, resulting in little predictability in what units of information might be found in the database.

Abstract

Subject classifications and thesauri have become more important than ever in the Web environment. Efforts made to organize information into subject classifications, or taxonomies, offer users the opportunity to substantially improve the effectiveness of their search and retrieval activities. This article continues earlier research an the development of a new definition of the field of information science and the creation of a "map" of the field showing subjects central to it and their relationships to those an the periphery. A case study describes the creation of a new classification structure (taxonomy) for the Information Science Abstracts (ISA) database, aiming to reflect and accommodate the rapid and continued technological and market changes affecting the information industry today and into the future. Based an a sample of some 3,000 ISA abstracts, two validation experiments were conducted by a three-member team comprising a database editor, a reference librarian, and an abstractor-indexer, who represent three of the major communities within the information science field. In the first experiment, the sample of abstracts was classified according to the proposed new taxonomy; alter analysis of the data and revision of the taxonomy, it was revalidated and fine tuned in a second experiment. Indexer consistency measures obtained in this study were significantly higher than those found in previous studies. The taxonomy resulting from this research employs the concepts, definition, and map of information science previously developed. It presents them in an organized hierarchical view of the field and thus makes a significant contribution to information science.

"Bibliographische Daten Um den Geltungsbereich der Prinzipien festzulegen, wird in diesem ersten Teil der zugrundeliegende Begriff bibliographischer Daten erläutert. Kerndaten Bibliographische Daten bestehen aus bibliographischen Beschreibungen. Eine bibliographische Beschreibung beschreibt eine bibliographische Ressource (Artikel, Monographie etc. - ob gedruckt oder elektronisch) zum Zwecke 1. der Identifikation der beschriebenen Ressource, d.h. des Zeigens auf eine bestimmte Ressource in der Gesamtheit aller bibliographischer Ressourcen und 2. der Lokalisierung der beschriebenen Ressource, d.h. eines Hinweises, wo die beschriebene Ressource aufzufinden ist. Traditionellerweise erfüllte eine Beschreibung beide Zwecke gleichzeitig, indem sie Information lieferte über: Autor(en) und Herausgeber, Titel, Verlag, Veröffentlichungsdatum und -ort, Identifizierung des übergeordneten Werks (z.B. einer Zeitschrift), Seitenangaben. Im Web findet Identifikation statt mittels Uniform Resource Identifiers (URIs) wie z.B. URNs oder DOIs. Lokalisierung wird ermöglicht durch HTTP-URIs, die auch als Uniform Resource Locators (URLs) bezeichnet werden. Alle URIs für bibliographische Ressourcen fallen folglich unter den engen Begriff bibliographischer Daten. Sekundäre Daten Eine bibliographische Beschreibung kann andere Informationen enthalten, die unter den Begriff bibliographischer Daten fallen, beispielsweise Nicht-Web-Identifikatoren (ISBN, LCCN, OCLC etc.), Angaben zum Urheberrechtsstatus, administrative Daten und mehr; diese Daten können von Bibliotheken, Verlagen, Wissenschaftlern, Online-Communities für Buchliebhaber, sozialen Literaturverwaltungssystemen und Anderen produziert sein. Darüber hinaus produzieren Bibliotheken und verwandte Institutionen kontrollierte Vokabulare zum Zwecke der bibliographischen Beschreibung wie z. B. Personen- und Schlagwortnormdateien, Klassifikationen etc., die ebenfalls unter den Begriff bibliographischer Daten fallen."

Abstract

A bibliography is traditionally characterized by the judgments, bounded by explicit selection criteria, made by a single compiler. Because these criteria concern the attributes ascribed to a work and the needs of readers, bibliographic work is largely conceptual even across technological eras and domains. Yet, the development of networked information services, made possible by WWW infrastructure, has enabled very large numbers of people to discover, organize, and publish information, including bibliographies. Indeed, bibliographies, or at least bibliography-like artifacts, are a common genre of website, often published by people without specialized skills in information organization who follow non-rigorous selection procedures. Nevertheless, even if the items from these lists are poorly selected and described, this publishing activity is fundamentally important because it structures information locally, creating a patchy network of secondary access points. In turn, these access points enable information discovery, the formation and development of communities of interest, the estimation of document relevance by search engines, and so on. In sum, this activity, and the enabling technical infrastructure, invites bibliographies to take on new interactive possibilities. The aim of this article is to extend the traditional view of bibliography to encompass collaborative possibilities for wide, or narrow, participation in the shaping of bibliographies and the selection of items. This is done by examining the nature of bibliography on the Web, by proposing a conceptual model that opens bibliography to participatory practices, and by discussing a case study where a team sought to develop a bibliography of electronic resources. This examination reveals splendid opportunities for expanding the notion of bibliography with participatory policies while remaining true to its ancient roots.

Abstract

In January 2010, the German National Library discontinued the print version of the national bibliography and replaced it with an online journal. This was the first step in a longer process of redefining the National Library's bibliographic services, leaving the field of traditional media - e. g. paper or CD-ROM databases - and focusing on publishing its data over the WWW. A new business model was set up - all web resources are now published in an extra bibliography series and the bibliographic data are freely available. Step by step the prices of the other bibliographic data will be also reduced. In the second stage of the project, the focus is on value-added services based on the National Library's catalogue. The main purpose is to introduce alerting services based on the user's search criteria offering different access methods such as RSS feeds, integration with e. g. Zotero, or export of the bibliographic data as a CSV or PDF file. Current standards of cataloguing remain a guide line to offer high-value end-user retrieval but they will be supplemented by automated indexing procedures to find & browse the growing number of documents. A transparent cataloguing policy and wellarranged selection menus are aimed.

Abstract

Die kostenfrei zugängliche Datenbank "Gesamtkatalog der Wiegendrucke" wurde am 20. August 2003 offiziell für die Fachwelt im Internet bereitgestellt. Ausgangspunkt für diese Datenbank ist die seit 1925 im Hiersemann Verlag in Einzelbänden erscheinende Druck-Version des "Gesamtkatalogs der Wiegendrucke", die weltweit sämtliche Drucke des 15. Jahrhunderts in alphabetischer Form nachweist. Der Gesamtkatalog der Wiegendrucke wird seit fast 100 Jahren in der Staatsbibliothek zu Berlin redaktionell bearbeitet. Bisher erschienen zehn Bände, die die Alphabetteile "A-H" umfassen. Dieses Material sowie die umfangreiche Materialsammlung der Redaktion, die nunmehr auch den Alphabetteil "I-Z" umfasst, wurde in den letzten Jahren mit Hilfe der Deutschen Forschungsgemeinschaft (DFG) elektronisch aufbereitet. Die Datenbank enthält unter anderem Angaben zum Umfang, zur Zeilenzahl, zu den Drucktypen sowie teilweise auch die Besitznachweise von Wiegendrucken. Anhand eines Verzeichnisses aller inkunabelbesitzenden Bibliotheken lassen sich die zum Teil spannenden Wege von Inkunabel-Sammlungen nachvollziehen. Die Suchmaschine ist keine übliche Web-Applikation. Sowohl Server als auch Klient laufen auf einem Applikations-Server in der Staatsbibliothek zu Berlin.

Abstract

This article presents examples of metadata collaborations between the Swiss National Library (NL) and research institutions in the field of Swiss historiography. The NL publishes the Bibliography on Swiss History (BSH). In order to meet the demands of its research community, the NL has improved the accessibility and interoperability of the BSH database. Moreover, the BSH takes part in metadata projects such as Metagrid, a web service linking different historical databases. Other metadata collaborations with partners in the historical field such as the Law Sources Foundation (LSF) will position the BSH as an indispensable literature hub for publications on Swiss history.

Abstract

A controlled set of searches have been conducted by a group of searchers, at Manchester Polytechnic Library, on a trial subset of the British National Bibliography (BNB) data base on both CD-ROM and on-line. Various measures of search effectiveness and effiency were examined in relation to the effect of the differing user interface, including recall, precision, search time, user satisfaction and other more subjective factors. Discusses the potential for further research on the evaluation of CD-ROM.

Abstract

The article focuses on the EBSCO databases that provide services to libraries. The Library, Information Science and Technology Abstracts (LISTA) include resources focusing on librarianship, classification, cataloging, bibliometrics, online information retrieval, and information science. LISTA has more than 21,000 articles from more than 600 periodicals and includes more than 5,000 conference papers and reports. In the database, there are also cited references and the number of times the source was used can also be found within the database. These are helpful tips in bibliography researching. The database has also several search options including "Basic Search," "Advanced Search," and Indexes." The EBSCOhost interface is simple to use and easy to grasp while LISTA is a free abstract database.

Am Hochschulbibliothekszentrum des Landes Nordrhein-Westfalen (hbz) wird seit Anfang 2014 nach Vorgaben und unter Begutachtung der Universitäts- und Landesbibliotheken in Düsseldorf, Münster und Bonn ein neuer Webauftritt für die Landesbibliographie Nordrhein-Westfalens, die Nordrhein-Westfälische Bibliographie (NWBib) entwickelt. Die Entwicklung basiert auf der Web-Schnittstelle des Linked-Open-Data-Dienst lobid und wird vollständig mit Open-Source-Software entwickelt. Aus der Perspektive des Entwicklungsteams am hbz beschreibt der Artikel Kontext und Durchführung des Projekts. Der Beitrag skizziert die historische Entwicklung der NWBib mit Fokus auf die Beziehung der Bibliographie zum World Wide Web (WWW), erläutert die Voraussetzungen für die Neuentwicklung sowie die Leitlinien des Entwicklungsprozesses, gibt einen Überblick über die Nutzung des neuen Webauftritts und die zur Umsetzung verwendete Technologie. Abgeschlossen wir der Artikel mit Lessons-Learned und einem Ausblick auf weitere Entwicklungen.
