Benefits of the proposed Common Command Language for online interactive information retrieval, which has been developed by the National Information Standards Organization, are discussed, as are remaining problems in cross-system searching. A summary of the language showing the functions performed by the various commands is included. (MES)

Eleven articles introduce expert systems applications in library and information science, and present design and implementation issues of system development for reference services. Topics covered include knowledge based systems, prototype development, the use of artificial intelligence to remedy current system inadequacies, and an expert system to…

Describes how online searchers can use a software tool based on back-of-the-book indexes to assist in dealing with search engine databases compiled by spiders that crawl across the entire Internet or through large Web sites. Discusses human versus machine knowledge, conversion of indexes to mind maps or mini-thesauri, middleware, eXtensible Markup…

This study was designed to be a state-of-the-art survey and investigation of intelligent "front end" design approaches and software for improving subject access and subject searching in today's large online bibliographic retrieval systems and online public access catalogs (OPACS). The report begins with an illustrated overview of…

This literature review selectively covers material on end-user searching published between 1971 and 1988. The first section discusses end-user search systems--e.g., multipurpose systems developed for end-users, simplified versions of traditional systems, gateway systems, and CD-ROM versions of databases. This section also discusses the complexity…

Describes the components and capabilities of expert systems, discusses the use of such systems in library information applications, and outlines research being done in this area. A project aimed at the development of an expert system for referral services is described in detail, and implications for future research are discussed. (CLB)

Summarizes four options for libraries that want to offer end user searching: end user systems (Bibliographic Retrieval Service's Afterdark, DIALOG's Knowledge Index); front-end microcomputer software (Sci-Mate Searcher, Pro-Search, WILSEARCH); gateway services (EASYNET); and local databases (now available on floppy and compact discs). Advantages…

This survey of the literature reveals user and professional opinions of changes in subject access features available for online public access catalogs. Highlights include expanded access to fields already incorporated into traditional MARC record, access to context of the record, and design of the user interface. Twenty-four references are cited.…

This study investigated the usefulness of end user systems to library and information science students. Seventeen volunteers were offered free searching on BRS/After Dark and DIALOG's Knowledge Index. The search itself, postsearch questionnaire, and completed research papers were analyzed for databases used, cost and time online, and precision.…

Search Helper, a microcomputer software package marketed by Information Access Company to serve as a gateway to several of their databases, was selected as a system for introducing the Carnegie-Mellon University community to do-it-yourself database searching. Preliminary results of user survey indicate service to be extremely popular with library…
