Defines and discusses bibliometrics, particularly as carried out in automated systems. The specific requirements to which data should conform to support bibliometric analysis are detailed and explained, and the Intelligent Gateway of the Lawrence Livermore National Laboratory is described.

This report outlines specifications for the online transaction monitoring and questionnaire administration features of the University of California's (UC) Prototype On-Line Catalog, known as MELVYL. The development and testing of these features by the UC Division of Library Automation (DLA) is also described. This document is the final report…

Presents analysis of online search patterns within user searching sessions of National Library of Medicine ELHILL system and examines user search patterns on the CATLINE database. Data previously analyzed on MEDLINE database for same period is used to compare the performance parameters of different databases within the same information system.…

Describes use of case study method to systematically develop model of online searching behavior in which study design is flexible, data gathering and analyses are determined by subject matter, and specific procedures are decided upon while study progresses. Problems and measures taken to reduce their effect are discussed. (Eleven references are…

This manual was produced to familiarize data users with the procedures followed in data collection and processing of the fifth follow-up survey of the National Longitudinal Survey of the High School Class of 1972 (NLS-72) and to provide documentation for use of the file. The data file is a computerized data base, which is available on magnetic…

Describes a model enumerating cost factors for comparing costs for paper, online, and CD-ROM indexes and abstracts. The model is applied to start-up and annual costs, and to the cost of storing and providing access to ERIC, Applied Science and Fisheries Abstracts, and Excerpta Medica, based on anticipated academic library usage.

This document outlines the methodology to be used for analyzing and reporting data collected through questionnaires at the various libraries of the University of California in April and May of 1982, as the second phase of an online public access catalog (OPAC) evaluation project. It is noted that the project was designed to enable systems…

These three users' manuals are for specific files of the High School and Beyond Study, a national longitudinal study of high school sophomores and seniors in 1980. The three files are computerized databases that are available on magnetic tape. As one component of base year data collection, information identifying twins, triplets, and some non-twin…

Presents a mathematical theory that can be used to define concentration places of objects within unordered classes. The application to research on the evolution of journals and subject areas is illustrated, and an online method of calculating concentration evolution is described. (1 references) (CLB)

Despite the best of intentions, qualitative researchers can be faced, in some circumstances, with having to make meaning from thin, or less than optimal, data. Using a real study as context, the authors describe the ways that they made sense of their thin data on teachers' perceptions of a large-scale evaluation instrument. They propose a…

Designed to characterize journals as part of the selection process for journals to be included in an information retrieval database, two studies used bibliometric techniques to examine patterns of publishing and topic patterns and coverage, and a third developed a rule-based system to evaluate the qualities of a journal.

Database documentation is provided for users of a data file consisting of a directory of all main public libraries in the United States. The directory development survey began with the mailing of a computer printout containing listings of each state's public libraries to the chief officer of the appropriate state library agency for updating. A…

The role of the coauthor relationship in the structure of informal communications networks within disciplines is explored, and the validity of coauthor graphs used to map these relationships is tested for both small and large databases. (CLB)

The Hepatitis Knowledge Base (text of prototype information system) was used for modifying and testing "A Navigator of Natural Language Organized (Textual) Data" (ANNOD), a retrieval system which combines probabilistic, linguistic, and empirical means to rank individual paragraphs of full text for similarity to natural language queries…

Suggests new method of external distribution called tree partitioning that involves use of binary tree to split incoming file into successively smaller partitions for internal sorting. Number of disc accesses during a tree-partitioning sort were calculated in simulation using files extracted from British National Bibliography catalog files. (19…
