    Abstract
    Reference librarians, who are thoroughly familiar with the purpose, scope and arrangement of abstract periodicals, are uniquely qualified for the task of writing abstracts. The procedures described here offer a relatively simple way for them to write acceptable abstracts from the outset. Although research is being conducted in the area of machine generated abstracts, there wll continue to be a role for human abstractors.

    Abstract
    Ausgehend von einer Diskussion der Gestaltungskonzeptionen und der Leistungsfähigkeit heutiger Volltext-Retrieval-Systeme wird ein Überblick über den Leistungsumfang des für die Aufbereitung und Präsentation von Textinformation zuständigen Systems TWRM-TOPOGRAPHIC gegeben. TWRM-TOPOGRAPHIC ist Teil eines neuartigen Informationssystems, das sich auf inhaltsorientierte Repräsentation von Volltexten stützt. Die beiden wesentlichsten Leistungsmerkmale von TWRM-TOPOGRAPHIC sind die graphische Retrievaldialogführung und die flexible, situationsgerechte Aufbereitung und Präsentation von Textwissen: Die Dialogführung erlaubt dem Benutzer die direkte Navigation in den auf dem Bildschirm graphisch dargestellten Wissensstrukturen, die Selektion dargestellter Objekte zur Formulierung einer Query sowie das Wechseln des Abstraktionsniveaus der dargestellten Textinformation. Die Aufbereitung und die Präsentation von Textwissen sind kognitiv-ergonomisch begründet und berücksichtigen sowohl die begrenzte Aufnahmekapazität der Benutzer als auch die Bedeutung der zeitlichen Anordnung von Informationseinheiten für die Wahmehmungs- und Gedächtnisleistung der Rezipienten. Textwissen wird in unterschiedlichen Abstraktionsstufen präsentiert: von einer sehr generischen Ebene über Wissensgraphen, automatisch generierten Abstracts bis zur diskursiven Form der Textpassage. Die Generierungskomponente des Systems leistet einen Beitrag zum situationsgerechten Systemverhalten dadurch, daß sie aus semantischen Text-Repräsentationsstrukturen unter Berücksichtigung textueller Wohlgeformtheitsbedingungen benutzerangepaßte Abstracts mit unterschiedlichem Themenschwerpunkt und variabler Ausführlichkeit produziert. Die Erprobung verschiedener LayoutVerfahren im Projekt TWRM-TOPOGRAPHIC wird durch ein flexibles, objektorientiert spezifiziertes User-Interface-Mangagement-System (UIMS) unterstützt, dessen Objektklassen und deren Interaktionsmöglichkeiten vorgestellt werden. Die Darstellung des Systems wird mit einem ausführlichen Dialogbeispiel abgeschlossen, das die Funktion des Interface und die Wirkung der drei zentralen Operatoren (Select, Zoom und Browse) im Retrievaldialog illustriert.

    Abstract
    A survey of abstracting policies by producers of bibliographical databases examined abstracting guidelines which aim to enhance free- text retrieval. Of the 123 database policies examined, fifty-seven (46 per cent) included such instructions. Editors consider contents of abstracts and their language as a primary factor in retrieval enhancement. Most recommend that once abstractors decide which concepts to include in abstracts and in which form to represent them, these terms should be co-ordinated with index terms assigned from a controlled vocabulary. Guidelines about the type of abstracts, i.e., informative or indicative, and about their length are not affected by the capability of free-text retrieval

    Abstract
    This study compares the quality of indexing in library and information science databases (Library Literature (LL), Library and Information Science Abstracts (LISA), and Information Science Abstracts (ISA)). An alternative method to traditional retrieval effectiveness tests, suggested by White and Griffith in their paper 'Quality of indexing in online databases' is adopted to measure the quality of the controlled vocabulary of each database ... Our analysis shows that LISA has the best quality of indexing out of the three databases

    Abstract
    An experiment was conducted using 3 data bases in library and information science - Library and Information Science Abstracts (LISA), Information Science Abstracts and ERIC - to investigate some of the main factors affecting on-line searching: effectiveness of search vocabularies, combinations of fields searched, and overlaps among databases. Natural language, controlled vocabulary and a mixture of natural language and controlled terms were tested using different fields of bibliographic records. Also discusses a comparative evaluation of single and multi-data base searching, measuring the overlap among data bases and their influence upon on-line searching.

    Abstract
    Indexing terms supplied by authors can increase subject control of their documents. The terms can be used in the creation of indexes, abstracts, and other devices for information retrieval in the special library. An examination of the American Mathematical Society author indexing program suggests that contributions of authors enhance indexing efforts of editors

    Abstract
    Examines the accepted principles of controlled indexing, in published abstracting/indexing services and databases from the unusual aspect of the publisher's need to minimize production costs. Detailed information concerning the producution of LISA is presented showing income and costs. Ways in which factors involved in controlled indexing may be seen to manifest themselves in production parameters are shown by plotting graphs of the numbers of abstracts and index pages against numbers of abstracts for 77 individual issues of LISA. The close fit of the data to straight lines, with correlation coefficients approaching unity, provides a means of managing the size of individual issues to yield minimum printing/binding costs. The extended use of the CRG classification notation to provide automatic extraction of chain indexing strings and associated cross-references is described in detail. The gains in staff productivity resulting from this and other procedures are indicated with reference to the expansion in LISA's coverage between 1978 and 1984.

    Abstract
    Nach einer kurzen Einführung in die DK wird die Verwendung einer computerisierten fassung der DK in einigen Institutionen beschrieben, wie z.B. in der Bibliothek der ETH Zürich oder beim Österreichischen Arbeiterkammertag. Abfragemöglichkeiten über die DK werden am Beispiel von drei datenbanken aus drei verschiedenen Hosts diskutiert. Es sind: Economic Abstracts (Host: DIALOG), VWWW (Host: DATASTAR) und MATHDI (Host: INKA). Die besonderen Schwierigkeiten bei komplexen DK-Zahlen werden diskutiert und es wird vorgeschlagen, einen Algorithmus zum Aufbau von DK-Zahlen zu erstellen.

    Abstract
    Ausgehend von einer Diskussion der Gestaltungskonzeptionen und der Leistungsfähigkeit heutiger Volltext-Retrieval-Systeme wird ein Überblick über den Leistungsumfang des für die Aufbereitung und Präsentation von Textinformation zuständigen Systems TWRM-TOPOGRAPHIC gegeben. TWRM-TOPOGRAPHIC ist Teil eines neuartigen Informationssystems, das sich auf inhaltsorientierte Repräsentation von Volltexten stützt. Die beiden wesentlichsten Leistungsmerkmale von TWRM-TOPOGRAPHIC sind die graphische Retrievaldialogführung und die flexible, situationsgerechte Aufbereitung und Präsentation von Textwissen: Die Dialogführung erlaubt dem Benutzer die direkte Navigation in den auf dem Bildschirm graphisch dargestellten Wissensstrukturen, die Selektion dargestellter Objekte zur Formulierung einer Query sowie das Wechseln des Abstraktionsniveaus der dargestellten Textinformation. Die Aufbereitung und die Präsentation von Textwissen sind kognitiv-ergonomisch begründet und berücksichtigen sowohl die begrenzte Aufnahmekapazität der Benutzer als auch die Bedeutung der zeitlichen Anordnung von Informationseinheiten für die Wahmehmungs- und Gedächtnisleistung der Rezipienten. Textwissen wird in unterschiedlichen Abstraktionsstufen präsentiert: von einer sehr generischen Ebene über Wissensgraphen, automatisch generierten Abstracts bis zur diskursiven Form der Textpassage. Die Generierungskomponente des Systems leistet einen Beitrag zum situationsgerechten Systemverhalten dadurch, daß sie aus semantischen Text-Repräsentationsstrukturen unter Berücksichtigung textueller Wohlgeformtheitsbedingungen benutzerangepaßte Abstracts mit unterschiedlichem Themenschwerpunkt und variabler Ausführlichkeit produziert. Die Erprobung verschiedener LayoutVerfahren im Projekt TWRM-TOPOGRAPHIC wird durch ein flexibles, objektorientiert spezifiziertes User-Interface-Mangagement-System (UIMS) unterstützt, dessen Objektklassen und deren Interaktionsmöglichkeiten vorgestellt werden. Die Darstellung des Systems wird mit einem ausführlichen Dialogbeispiel abgeschlossen, das die Funktion des Interface und die Wirkung der drei zentralen Operatoren (Select, Zoom und Browse) im Retrievaldialog illustriert.

    Abstract
    Presents a detailed evaluation of the CD-ROM data base Library and Information Science Abstracts (LISA), published by Library Association Publishing Ltd in partnership with SilverPlatter Information Inc. Describes the SilcerPlatter search software and gives results of test searches carried out using the CD-ROM and DIALOG on-line versions of LISA. The annual cost of subscribing to LISA on CD-ROM is 995 US dollars or 750 dollars to subscribers of other SilverPlatter data bases. LISA on CD-ROM will be of most interest to institutions which make heavy use of the on-line version and are not discouraged by the low updating frequency.
