Explores the potential usefulness of the Library of Congress Classification (LCC) system as a tool in online retrieval. Unique features of LCC are described and a theoretical analysis of its potentials and limitations in terms of subject browsing, enhanced vocabulary, and class number searching are presented. (CDD)

This review of the research on the use of card catalogs and online catalogs highlights research methodologies and significant findings. Discussion of the results focuses on user needs and satisfaction, and the need to separate bibliographic practices that are universally sound from those that are an adaptation to the medium. (CLB)

This review of the literature on the effect of information overload on users' information-seeking behavior focuses on librarians' opinions about the number of references that constitute too many, and users' preferences for maximum numbers of references from online searches, online public access catalog postings, and manual indexes. (35 references)…

Summarizes the growth of databases, including major milestones, issues, and trends of the past 20 years, during which time the database/online industry had become a large and thriving segment of the information industry. A time line overview of database developments from 1951 to 1985 is appended. (42 references) (EJS)

Discusses forces at work within today's on-line data base environment which could lead to the emergence of a distributed information network; identifies several important modules in such a network, including an automated subject switching module; and reports research investigations, critical issues, and preliminary findings with regard to…

Presents a cognitive model that provides a user-centered perspective of the information retrieval process and confirms the problematic nature of online library catalogs for children. Related research is reviewed, and it is concluded that developing children's thinking skills will help them search for information. (71 references) (Author/LRW)

Outlines a behavioral approach to information retrieval system design based on the derivation of a behavioral model of the information-seeking patterns of academic social scientists. The extent to which identified information-seeking characteristics are supported by existing systems is considered, and requirements for implementing these features…

Reviews the use of artificial intelligence research techniques to create tools that can assist with ongoing library functions and with information skills both within and outside of the library setting. Major areas discussed include cataloging, indexing, database searching, reference services, knowledge acquisition and representation, user…

Discusses the concept of search failure in document retrieval systems and three effectiveness measures, precision, recall, and "fallout." Four research methods--retrieval effectiveness measures, user satisfaction measures, transaction log analysis, and critical incident technique--are examined, and findings of major studies using each of the…

Discusses an experiment with the "Thesaurus of ERIC Descriptors" which aimed to adapt established criteria for the evaluation of information retrieval systems to the assessment of searcher performance in online bibliographic searching. The concept of relevance is discussed, and the Cranfield paradigm for the evaluation of information…

Review of the 1991 literature on subject access in online systems discusses users and subject searching; subject access in online catalogs, including improvement of the database, search processing, the user interface, and user understanding; subject cataloging and indexing; information retrieval; thesaurus and indexing approaches; classification;…

A meta-analysis procedure was used to review research on pictorial effectiveness which focused on the use of static iconic visuals in instructional materials. The purpose of this exploratory study was to provide a means for forming future hypotheses based upon a quantitative aggregation of past research. The study was concerned with differential…

Discusses the use of optical disk technology in online searching and compares three versions of the ERIC database currently available on optical disk in terms of hardware requirements, ease of installation, scope and cost of the system, search procedures, displaying and printing results, and documentation and user support. (CLB)

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…

Description of classification schemes for fiction book retrieval covers traditional methods, universal systems, special systems, genre systems, and development of the AMP-classification system based on multidimensional analysis of users' requests (subject matter, setting, author's intention, accessibility). Trial applications and retrieval tests,…
