Describes an experiment that was designed to compare three different map displays used as a visual display for information retrieval by either a self-organizing algorithm or human subjects. Results indicate that the organization and visual appearance of map displays had a significant effect on subjects' searching and browsing on the map displays.…

Describes a study that investigated fifth-grade children's search behavior using an automated library catalog designed for children called the Science Library Catalog. Level of science domain knowledge was found to influence both their success and search behavior. (Author/LRW)

Discussion of the Global Information Infrastructure (GII) focuses on a longitudinal study conducted in Central and Eastern Europe that investigated two issues: (1) the relationship between computing networks and library automation in establishing a national information infrastructure, and (2) requirements for library automation for exchanging…

Describes the development of a taxonomy of the value of library services based on users' assessments from five large research libraries. Highlights include empirical and derived taxonomy, replicability of the study, reasons for using the library, how library services are related to time and money, and a theory of value. (LRW)

Examines whether the paper-medium structure of the major classics bibliography, "L'Annee Philologique", validly reflects information retrieval paradigms of individual classicists. Faculty and graduate student attitudes toward and use of features of the paper-medium form are discussed, and attitudes toward the upcoming CD-ROM version are examined.…

Discussion of indexing as a problem-solving activity focuses on an experiment that applied theories and methods from cognitive psychology to study interindexer consistency. Eight indexers (four novice and four experts) used two thesauri to index the same four documents. Three kinds of verbal reports were used to assess cognitive processes. (LRW)

Explains how indexers choose keywords and how results can differ between indexers by focusing on certain properties of the terms rather than on the terms themselves. Based on research in semiotics, cognitive science, discourse analysis, and reading theories. Indexing terms from 833 bibliographic records from an environmental database are analyzed.…

Describes a study that collected data on information needs and uses during Internet training from students in information networking classes at Indiana University. Information needs, events which led to the needs, and the sources used to resolve the needs were identified and categorized, and implications for Internet trainers are discussed.…

This report includes data on the cognitive and affective behavior of college students who were given the tasks of interpreting and formulating Boolean search statements. Two versions of written point-of-use instructions on Boolean searching, affectively elaborated and unelaborated, were given to investigate comprehension, self-confidence, and…

Results are reported from a study that investigated the extent to which academic library end users conducted multiple search sessions with online public access catalogs or CD-ROM databases at different stages of their information seeking related to a research project. Implications for training, retrieval systems design, and further research are…

Examines the transition from traditional single database retrieval to the emerging networked resources retrieval, and presents research and experimental solutions developed at the University of California, Berkeley. Highlights include recall and relevance, network navigation, vocabulary, and extending retrieval records. (LRW)

This progress report presents findings from a failure analysis of two full-text computer-assisted legal research systems, Lexis and Westlaw. Linguistic analyses of unretrieved documents and false drops are discussed, and examples of natural language phenomena that affect Boolean retrieval system performance are examined. (Author/LRW)

Describes a study that investigated search intermediaries' requests for information from patrons during mediated online searching in an academic library. Topics of search intermediaries' elicitations include search terms and strategies, database selection, relevance of retrieved items, patrons' knowledge and previous information seeking, and other…

Compares two empirical studies that examined user-defined relevance criteria in order to identify criteria that span information environments as well as criteria that are more situationally specific. One study used an academic environment with printed materials; the other studied occupational users of multimedia materials. (Author/LRW)

Describes a task-oriented assessment of two MEDLINE searching systems by medical students, one using Boolean searching on human-indexed thesaurus terms and one using natural language searching on words in the title, abstract, and indexing terms. Highlights include user certainty in answering questions, time needed, and user satisfaction.…
