When examined across studies and fields, navigation research is fragmented and inconsistent. In this article, we argue that this is the result of navigation research having generally been conducted without guidance from an overarching theoretical framework. In order to illustrate our position, we have included results from a very simple…

Describes a study that examined the effectiveness of implied boolean searches using personal author surnames plus first and/or last title words to retrieve an entry from a simulated online public access catalog (OPAC). Implications for the design of OPACs are discussed, and further research is suggested. (LRW)

Discusses ways in which artificial intelligence could be applied to improve the ease of use, quality of retrieval, and organization of data in online services or CD-ROM. (MES)

Discusses the issues influencing the design, implementation, and promotion of the Towers Perrin in-house text retrieval system. The discussion of factors influencing system design includes the organizational culture, the existing computer and communications network, and the availability of text retrieval software. Suggestions for in-house systems…

Describes two experiments that investigated the influence of textual factors on the perception of bibliographic records. Topics include index descriptors; term overlap; extent of semantic distance; direction of semantic distance; generic trees of descriptors; relevance perception; and implications for the design of information retrieval…

Discusses client-server architecture in dumb terminals, personal computers, local area networks, and graphical user interfaces. Focuses on functions offered by client personal computers: individualized environments; flexibility in running operating systems; advanced operating system features; multiuser environments; and centralized data…

Describes a prototype interactive science catalog for children that will have three interfaces: a subject-oriented browsing search, a search tied directly to science simulations, and an author/title/subject keyword searchable interface. Research plans include examinations of children's abilities to formulate and implement searchable queries and…

Describes the implementation and first year's operation of the online end-user bibliographic data service created for United Kingdom academic libraries, the Bath Information Data System (BIDS ISI), which was created in cooperation with the Institute for Scientific Information. Assesses its impact on the activities of computer centers, libraries,…

Three articles discuss the second online library system at the University of Hawaii at Manoa--the CARL (Colorado Alliance for Research Libraries) System. Topics addressed include an overview of the system; development of a Windows-based CARL cataloging workstation; and incorporating digitized images in the online public access catalog. (EA)
