The online catalog discussed in this report extends the present microfiche union catalog development by providing online access to bibliographic records for the holdings of the University of California Libraries. The specifications for the user interface through which the library patron communicates with the online systems to locate materials are…

Discusses search requests in information retrieval systems and describes the development of an algorithm for the automatic construction of query formulations in Boolean form. Topics discussed include user needs, information retrieval languages, online systems, design requirements for the algorithm, and algorithmic functioning in information…

Presented in this executive summary are some extracts to highlight the five parts of a report that investigated the online use of the Educational Resources Information Center (ERIC) data base and the impact of free text or controlled vocabulary searching on its design. Included is a collection of all the suggestions and recommendations for the…

Provides overview of design requirements for transparent information retrieval (implies that user sees through complexity of retrieval activities sequence). Highlights include need for transparent systems; history of transparent retrieval research; information retrieval functions (automated converters, routers, selectors, evaluators/analyzers);…

Discusses the definition of an online library catalog; five factors to be considered by the online catalog designer; user-computer communication (error messages, help screens, prompts, unnatural language); online tutorials and offline instruction offered by bibliographic instruction librarians; and the current situation. Nine references are…

This report focuses on a discussion of findings from analyses of computer transaction logs contributed by four of the online catalog systems used in the Public Access Project. It supplements the analyses of User and Non-User Questionnaires by providing analyses of data from the systems themselves. The four systems contributing data to this…

Discusses the design of interfaces for online systems and suggests requirements that must be met to offer maximum aid to inexperienced users. Highlights include the online search process, user data, query processing, database descriptors, semantic links, multilingual processing, search strategies, and distributed systems. A 20-page bibliography…

The Subject Access Research Project was initiated by OCLC in August 1979 to study the process of subject searching in the library catalog, with the objective of identifying features for an automated subject retrieval system which would support the present search tactics employed by library users performing manual subject searches at the library…

This report addresses the objectives of a national survey of users and non-users of online catalogs (OPAC's) as they apply to MELVYL and its implementation in the University of California (UC) Libraries on nine campuses. These objectives were to collect information to enable libraries to improve implementation of support services for public access…

Presents results of five experiments on human information-seeking behavior in different online information-seeking environments which studied search strategies and assessed information value in realistic search environments. A conceptual model of how humans value information is presented. Empirical and modeling results are considered for…

The variety of searchable and printable formats of Educational Resources Information Center (ERIC) data base records has led to different searching methods, which have fostered the confusing state of affairs wherein different results are possible for the same search; this 5-part report describes an investigation of ERIC online use that studied the…

This paper examines the search and selection strategies of teachers when retrieving information on computer assisted learning programs from an online database. A literature review covers cognitive factors in human computer interactions, database query and manipulation, cognitive style, and information searching. Several experiments are reported…
