Abstract

Presents a brief, critical review of LISA PLaus: the CD-ROM database version of LISA and which includes the database of Current Research in Library and Information Science (CRLIS). The review covers the DOS version only, as it appeared in the Summer 1996 CD-ROM, noting that the Windows version was planned for the future. Points to the way LISA has found its mark, if not its fortune, in LISA Plus and notes its strengths, including: ideal suitability for current awareness in library and information science (LIS); massive and convenient consolidation of the published LIS literature; and massive increase in coverage from 7.900 abstracts in 1993 to over 12.000 currently. Criticizes certain features of LISA Plus, notably: the OPTI-Ware search interface; the combination of 2 databases (LISA and CRLIS) in a single, searchable database; and certain unexpected effects caused by the building of the Subject and Free Text indexes. Points particularly to great lack of consistency in the indexes and the indexing (faults that were fully rectified by a complete overhaul of the data in Summer 1996). Notes that LISA Plus is the first port of call for both information researchers and information science students. The Windows version of LISA Plus was launched in Spring 1997

Abstract

Describes an experiment using 48 sixth-grade students to compare retrieval techniques using the print and CD-ROM versions of Compton's Encyclopedia. Four queries of defferent complexity (measured by the numer of terms present) were searched by the students after a short training session. The searches were timed and the retrieval steps and search terms were noted. The searches were no faster on the CD-ROM than the print version, but in both cases time was related directly to the number of terms involved. The students coped well with the CD-ROM interface and its several retrieval paths

Abstract

In der vorliegenden Arbeit werden 4 Abfrageoberflächen unterschiedlicher Retrievalsysteme, die für die Mitarbeiter des Umweltbundesamtes Berlin zugänglich sind, im Hinblick auf Nutzerfreundlichkeit und intuitiver Bedienbarkeit vergleichend untersucht. Der 'Einfachdialog' und die Oberfläche der 'Umwelt-CD' greifen auf die Datenbestände der Umweltdatenbanken zu. Berücksichtigt werden hierbei die Oberflächen zur Recherche in ULIDAT und UFORDAT. Das Metadatensystem UDK (Umweltdatenkatalog) wird in der PC-Version, dem 'UDK-UBA', und in der WWW-Variante in die Untersuchung einbezogen

Abstract

Evaluates 2 academic encyclopedias on CD-ROMs: Encyclopedia Britannica, and Encyclopedia Americana. Both are reasonably priced. Covers: search interface, subsets (both include Merriam-Webster Collegiate Dictionay, the Britannica includes Propedia, and Nations of the World, and the Americana Chronology of World History) and illustrations

Abstract

Suggests techniques and evaluation criteria for information sources and services available on the Internet. The need for qualitative judgements about library materials and information sources is upheld and accepted techniques and evaluation criteria for printed reference works are outlines. The emergence of non-book materials and electronic information formats has created the need for new techniques and criteria relating specifically to online services and CD-ROM products. Use of the Internet by library and information workers is examined, establishing that the majority of current traffic is communications-based. The authors suggest that networked information sources require the development of additional techniques and criteria for evaluation if they are to be used by information professionals. The potential issues in establishing such a list are discussed
