Reports research undertaken to conceptualize, design, and implement a system for automatic indexing, classification and repositing of "text items," which may be any aggregate of information in English Language on a computer-readable media, in a standard format. (Author)

Discusses categorization of MARC records, noting problems which arise because formats have not been defined as distinct sets of content designators. Bibliographic and authority record formats, merging of formats into single format, removal of inconsistencies, and criteria for identifying categories of records are considered. Thirty-one references…

An investigation of the feasibility of using a computer-assisted decentralized bibliographic control system to build a comprehensive, consistent national database for use in a national library network used the Northwestern On-line Total Integrated System to establish a center for African materials at Northwestern University. Eleven references are…

Reports the results of experiments using colon classification for the analysis, representation, and retrieval of primary information from the full text of documents. Recall, precision, and search length measures indicate colon classification did not perform significantly better than Boolean or simple word occurrence systems. Thirteen references…

A meeting was held to explore critical issues and problems related to subject access to online bibliographic records of monographic literature. The 23 researchers, practitioners, and policymakers who attended represented national and research libraries, bibliographic utilities, database vendors, library schools, indexing and abstracting services,…

This data tape--NCES.HEGIS.TAXONOMY.FILE1981--represents a crosswalk between the old taxonomy of the Higher Education General Information Survey (HEGIS) and the newer taxonomy of the Classification of Instructional Programs (CIP). The 838 records give the old taxonomy and 4-digit codes and the new taxonomy and 6-digit codes for the conventional…

This examination of abstracting-indexing services for the field of history focuses on Historical Abstracts (HA) and America--History and Life (AHL), and their relationship to the American Bibliographical Center's Subject Profile Index (ABC-SPIndex). The history, scope, selection criteria, and classification arrangements of the two databases are…

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)

Emphasizes class maintenance of National Library of Medicine's bibliographic retrieval file in which maintenance actions (replacement, deletion, addition) reflect yearly changes in Medical Subject Headings (MeSH). File maintenance of other authoritative information attached to headings, class maintenance failures, checking class maintenance,…

This comparison of bibliographies/online databases regarding their classification schemes, periodicals list, coverage of articles, indexing, and overlap reveals that only five bibliographies cover whole of subject area, and differences exist between number of periodicals scanned (73 to 2,771) and percentage of articles included from six…

Reviews the subject access literature for 1988 in the format of an annotated bibliography. Topics covered in the review include online subject access, standard subject heading lists, proposed alternatives to subject heading lists, authority work, classification schemes, and new product information. (CLB)

This document is the newest revision of the third manual documenting the National Agricultural Library database. Since it began in 1970, the AGRICOLA database has continued to grow and to change steadily; new subfiles have been added, database record formats have been expanded, and subject category code schemes have been modified several times.…

This paper examines inclusive design delivery through interface design, with a particular focus on access to healthcare resources for seniors. The goal of the project was to examine how seniors are able to access drug information using two different online systems. In the existing retrieval system, pills are identified using a standard search…

Focuses on indexing refinements in major life science databases--those specializing in biological/biomedical literature coverage--which influence cross-life searching decisions. Tables included highlight database descriptions, comparisons in coverage, ease of access (indexing of secondary concepts or search modifiers), chemical substance indexing…

A new search feature has been developed and implemented to enhance online information retrieval from the ABI/INFORM database, which includes abstracts from more than 500 journals covering all aspects of business and management. Published by Data Courier Inc., it includes material dating back to 1971. Because of the diverse nature of the database…
