Discusses the effect of online library catalogs on when, how, and by whom authority control work is done, focusing on experiences at Ohio State University Libraries. Shifts include removal of authority work from automated cataloging procedures, separation of mechanical and intellectual tasks, unique headings and references, and original…

This review of the overall findings of the "Educating the Online Catalog User" project at Northwestern University Library focuses on methods of data collection used in evaluating online catalog performance and user performance. The rationale and methodology of transaction log monitoring and new directions for technical development are…

Describes a model which uses patron arrival rate, length of time on the terminal, and library service policies to determine the minimum number of terminals needed. The model is then used to compare the effects of various service policies on the minimum number of terminals. (CLB)

Using a basic vocabulary and simple model, this paper discusses four options available at the level of the individual bibliographic database for resolving conflicts in MARC exchange: addition, deletion, modification, and superimposition. Costs and benefits of each option and impacts on MARC exchange are noted. (Fourteen references are cited.) (EJS)

Describes a technique for accessing a library system with limited interconnectivity by connecting the system to a gateway machine that is a host in the local area network and evaluates the performance of an existing prototype that has been implemented at the Los Alamos National Laboratory. (Author/CLB)

Reports the methodology and results of a study which explored the potential of three approaches to sampling the Australian Bibliographic Network (ABN) database files for determining collection overlap among Australian libraries. (Author/CLB)

Examines the factors that determine the cost of retrospective conversion (definition of conversion, standards of acceptance, method of conversion, hit rate, standards for creation of machine-readable records for nonhits); reports results of cost study at University of Michigan library; and introduces an alternative strategy for discussion. Seven…

Description of the way in which some essential features of pathfinders have been incorporated in the online library catalog at Lehigh University discusses factors involved in record design, provides examples of records used with a GEAC Integrated Library System, and suggests several ways of implementing pathfinder records online. (CDD)

This article discusses tools developed to aid the systems analysis process (program evaluation and review technique, Gantt charts, organizational charts, decision tables, flowcharts, hierarchy plus input-process-output). Similarities and differences among techniques, library applications of analysis, structured systems analysis, and the data flow…

A survey at the University of Houston examined factors related to subject searching success in online catalogs, including: extent of subject searching; response to unsuccessful searches; reasons subject search is not used; users' awareness of sources of subject terms; and suggestions from users for improving subject searching capabilities. (CLB)

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)

Reports on the Online Catalog Public Access Project, a survey of users and nonusers in 31 U.S. libraries conducted for the Council on Library Resources. Characteristics of users, tasks, library setting, and system interface that affect user satisfaction are identified. A 25-item bibliography and user questionnaire are appended. (7 references) (EJS)
