Presents a new model of searching in online and other information systems, and reviews the literature of manual information seeking behavior for suggestions of capabilities users might like in online systems. Based on the model--called "berrypicking"--and research, suggestions are made for how new search capabilities could be implemented…

This report presents a model combining the emerging technologies of hypertext and expert systems. Hypertext is relatively unexplored but promises an innovative approach to information retrieval. In contrast, expert systems have been used experimentally in many different application areas ranging from medical diagnosis to oil exploration. The…

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…

Issues concerning the implementation of standard user interfaces for CD-ROMs are discussed, including differing perceptions of the ideal interface, graphical user interfaces, user needs, and the standard protocols. It is suggested users should be able to select from a variety of user interfaces on each CD-ROM. (EA)

Describes the redesign of a CD-ROM database interface by the Congressional Information Service (CIS) that addressed the needs of novice, casual, and expert searchers in academic libraries. Topics discussed include the user profile, the task profile, redesign goals, interaction style, menu design and implementation, system structure and the search…

Human-computer interface design concepts are used as the criteria for evaluating the benefits and shortcomings of San Diego State University Library's online catalog, INNOPAC (the PAC). Features discussed include integrated files, search capabilities, system availability, user interface, record-to-record links, boolean operations, subject access,…

This continuation of an earlier article discusses online vendors' responses to users' concerns as well as the future of online services. Maxwell Online, Dialog, Mead Data, Data-Star, and Dow Jones News/Retrieval address user needs, search strategies, databases, document retrieval and display, user interface, and cost and economic issues.

This report focuses on the user of a prototype hypertext application designed to help coin collectors link ancient coins with relevant numismatic information. It is noted that hypertext systems promote the collection of information that may be multimedia in nature and may be linked so that information can be accessed in a non-linear manner. The…

Describes a specialist bibliographic database of literature in the field of artificial intelligence created by the Turing Institute (Glasgow, Scotland) using the BRS/Search information retrieval software. The subscription method for end-users--i.e., annual fee entitles user to unlimited access to database, document provision, and printed awareness…

The experiences of novice users (freshman students at Ohio University) searching OCLC's FIRSTSEARCH set of databases were studied. The 13 subjects were asked to complete a search on the FIRSTSEARCH databases; and data were collected through observations, administration of a questionnaire, and a thinking-aloud protocol. Data were analyzed to…

Describes the development of the Naval Research Laboratory (NRL) library information network which provides NRL scientists with access to CD-ROM databases, electronic journals, software applications, the Internet, and the library's online catalog. Implementation phases, system research and development, CD-ROM networking feasibility analysis,…

Considers factors central to the design, specification, and implementation of a private bibliographic database for the documentation of internally generated techno-commercial reports at PA Technology, a scientific and technical consulting company. A survey of subject access and indexing needs, hardware and software design, and possible future…

Describes the alternatives used by the Penn State University libraries to respond to the challenge of providing access to the many different kinds of databases. Approaches include development of a generic interface based on the Z39.50 protocol; staff support, including instruction, reliable documentation, and staff involvement; and better user…

The emphasis of this text is that the problems of information retrieval are the intellectual ones of subject analysis and description. These problems are not easily solved by technology alone, although certain inroads are being made by knowledge-based expert systems and other computer aids to indexing. Linguistic approaches are also showing…
