    "Der etwas provokante Titel soll keineswegs eine Dichotomie zwischen bibliothekarischer und nutzerorientierter Erschließung implizieren, sondern zwei Fragen stellen: Was suchen Nutzer in Bibliotheken? Was wollen Nutzer wissen? Die Antwort darauf wird immer heißen: Nutzer suchen nach Inhalten und wollen Informationen über Inhalte. Formale Aspekte, die unter bibliothekarischen Gesichtspunkten durchaus bedeutend sind, spielen für den Nutzer keine große Rolle, Schlagworte als Instrumente der verbalen Sacherschließung beschreiben Inhalte häufig unzureichend und sind für Nutzer vielfach unverständlich. Die bunten Kataloge der Internet-Buchhändler stellen zunehmend einen Kontrast, aber auch eine Konkurrenz zu unseren OPACs dar. Wer in diesen Katalogen recherchiert, findet zwar meist nur eine rudimentäre und natürlich bibliothekarischen Kriterien nicht entsprechende Titelbeschreibung, dafür jedoch regelmäßig zusätzliche Informationen wie Abstracts oder Verlagsinformationen, Rezensionen, Abbildungen, Textproben. Sollen wir uns nun den Katalog von Amazon.de (und seiner Konkurrenten) zum Vorbild nehmen? Wir meinen ja und erfassen daher Abstracts und andere Inhaltsinformationen, die wir mit unseren Titelaufnahmen im Verbund verlinken. Wir sehen darin eine Fortsetzung unseres seit einigen Jahren verfolgten Zieles, die traditionelle Sach- und Formalerschließung um neue Komponenten zu erweitern. Seit 1997 beteiligen wir uns an der kooperativen Aufsatzerschließung, insbesondere durch die Katalogisierung von Festschriftenaufsätzen. Aufsätze in fortlaufenden Sammelwerken katalogisieren wir nur ausnahmsweise, jedoch weisen wir von den Verlagen im Internet angebotene Inhaltsinformationen über Zeitschriften (Inhaltsverzeichnisse, Abstracts, Volltexte) auf der lokalen Ebene nach. Mit unserem Versuch, Abstracts in eine Datenbank des Verbundes einzustellen, haben wir Ende 2000 begonnen. Von ausgewählten Monographien werden Klappentexte, Verlagsinformationen und Abstracts erfasst und mit der Titelaufnahme verlinkt. Unser bisheriges Verfahren ist handgestrickt - hat aber den Vorteil, dass es ohne zusätzliche Technik auskommt und unmittelbar umsetzbar ist: In einem ersten Schritt werden Klappentexte und Inhaltsinformationen von geeigneten Werken ausgewählt. Die Auswahl berücksichtigt sowohl die Bedeutung des Buches wie Umfang und Qualität der Inhaltsinformationen. Das Erfassen der Texte geschieht durch Einscannen oder - wenn dies bei kurzen Texten effizienter ist - durch Abschreiben. Bei einzelnen Verlagen ist es möglich, die Texte direkt von den Webseiten des Verlages per copy-and-paste zu übernehmen. Die Doktoranden unserer Fakultät bitten wir um die Lieferung des Abstracts als Textdatei. Die durch Einscannen, Abschreiben oder Kopieren erzeugte Textdatei wird im nächsten Schritt in eine vom BSZ entwickelte Muster-HTML-Datei kopiert, konvertiert und mit der SWBIdentnummer versehen. Anschließend senden wir diese Datei per E-Mail an den Verbund. Der Verbund stellt unsere Dateien in den BSZ-Medienserver (http://www.bszbw.de/diglib/medserv/metainfhtml) ein, auf dem z.B. auch die ebenfalls mit den VerbundTiteldaten verlinkten IfB- und ekz-Rezensionen gespeichert werden."

    Abstract
    Comments on the value of abstracts or summary notes to information available online via the Internet and WWW and concludes that automated abstracting techniques would be highly useful if routinely applied to cataloguing or metadata for Internet documents and documents in other databases. Information seekers need external summary information to assess content and value of retrieved documents. Examines traditional models for writers, in library audiovisual cataloguing, periodical databases and archival work, along with innovative new model databases featuring robust cataloguing summaries. Notes recent developments in automated techniques, computational research, and machine summarization of digital images. Recommendations are made for future designers of cataloguing and metadata standards

    Abstract
    Abstracts from 7 Internet subject trees (Euroferret, Excite, Infoseek, Lycos Top 5%, Magellan, WebCrawler, Yahoo!), 5 Internet subject gateways (ADAM, EEVL, NetFirst, OMNI, SOSIG), and 3 online databases (ERIC, ISI, LISA) were examined for their subject content, treatment of various enriching features, physical properties such as overall length, anf their readability. Considerable differences were measured, and consistent similarities among abstracts from each type of source were demonstrated. Internet subject tree abstracts were generally the shortest, and online database abstracts the longest. Subject tree and online database abstracts were the most informative, but the level of coverage of document features such as tables, bibliographies, and geographical constraints were disappointingly poor. On balance, the Internet gateways appeared to be providing the most satisfactory abstracts. The authors discuss the continuing role in networked information retrieval of abstracts and their functional analoques such as metadata

    Abstract
    Die vorliegende Auswahlbibliographie ist in 9 Themenbereiche unterteilt. Der erste Abschnitt enthält Literatur, in der auf Abstracts und Abstracting-Verfahren allgemein eingegangen und ein Überblick über den Stand der Forschung gegeben wird. Im nächsten Abschnitt werden solche Aufsätze referiert, die die historische Entwicklung des Abstracting beschreiben. Im dritten Teil sind Abstracting-Richtlinien verschiedener Institutionen aufgelistet. Lexikalische, syntaktische und semantische Textkondensierungsverfahren sind das Thema der in Abschnitt 4 präsentierten Arbeiten. Textstrukturen von Abstracts werden unter Punkt 5 betrachtet, und die Arbeiten des nächsten Themenbereiches befassen sich mit dem Problem des Schreibens von Abstracts. Der siebte Abschnitt listet sog. 'maschinelle' und maschinen-unterstützte Abstracting-Methoden auf. Anschließend werden 'maschinelle' und maschinenunterstützte Abstracting-Verfahren, Abstracts im Vergleich zu ihren Primärtexten sowie Abstracts im allgemeien bewertet. Den Abschluß bilden Bibliographien

    Abstract
    Reports on one area of research in an Electronic Libraries Programme (eLib) MODELS (MOving to Distributed Environments for Library Services) supporting study in 3 investigative areas: examination of current database producers' guidelines for their abstract writers; a brief survey of abstracts in some traditional online databases; and a detailed survey of abstracts from 3 types of electronic database (print sourced online databases, Internet subject trees or directories, and Internet gateways). Examination of database producers' guidelines, reported here, gave a clear view of the intentions behind professionally produced traditional (printed index based) database abstracts and provided a benchmark against which to judge the conclusions of the larger investigations into abstract style, readability and content

    Abstract
    Summarizing is the process of reducing the large information size of something like a novel or a scientific paper to a short summary or abstract comprising only the most essential points. Summarizing is frequent in everyday communication, but it is also a professional skill for journalists and others. Automated summarizing functions are urgently needed by Internet users who wish to avoid being overwhelmed by information. This book presents the state of the art and surveys related research; it deals with everyday and professional summarizing as well as computerized approaches. The author focuses in detail on the cognitive pro-cess involved in summarizing and supports this with a multimedia simulation systems on the accompanying CD-ROM
