Subroutines which provide efficient access to a directly organized file by blocking and deblocking variable length bibliographic records are described. (Author)

Review and discussion of the techniques of automatic format recognition (AFR) of bibliographic data. Comparison of record-building facilities of Library of Congress, University of California (both AFR techniques), and Ohio College Library Center (non-AFR). Projection of a next logical generation, original format recognition. (Author/LS)

Libraries, as well as larger information networks, are necessarily based upon the storage of information files consisting in many cases of written materials and texts such as books, serials, abstracts, manuscripts and archives. At the present stage of the "information explosion" no librarian can afford to ignore the contribution of…

The BIBCON file management system, designed for use on IBM 360 system equipment, performs two basic functions: (1) it creates MARC structured, bibliographic records from untagged input data; (2) from these records it produces page image output for book catalogs. (7 references) (Author)

A description is presented of the project of the University of California Library Automation Program to cumulate the 1966 through 1971 supplements to the Library of Congress Subject Headings. (4 references) (Author)

Designed to provide guidance in selecting appropriate software for library automation, information storage and retrieval, or management of bibliographic databases, this inventory describes 188 computer software packages. The information was obtained through a questionnaire survey of 600 software suppliers and developers who were asked to describe…

Heavy emphasis was placed on experiments, and interpretation of experimental results. A set of experiments was designed to yield quantitative information on how the experimental subjects used the full-text-access system, why they used it and how effective it was. A detailed report of work on this topic to date is presented. The in-depth analysis…

An ensemble of information systems being developed by the Central Library and Documentation Branch of the International Labour Office, a specialized agency of the U.N. located in Geneva is described. ISIS (Integrated Scientific Information System) was designed and is now being used to assist in the provision of library and documentation services,…

The ways in which digital computers can be used in information storage and retrieval are presented in the language of the nonspecialist. Indexing methods, file organization, and search strategies are discussed and a brief bibliography containing 30 IBM publications is given. The manual is intended as a first reader for those interested in the…

User experiments are the main theme of this tenth issue in the series of Project Intrex semiannual activity reports. This system is undergoing tests with users who are motivated by their need for information rather than an interest in the machinery by which it is stored, retrieved and presented. Test results will indicate which fields in the…

Intended for teaching applications programing for libraries and information centers, this volume is a graded workbook or text supplement containing typical practice problems, suggested solutions, and brief analyses which emphasize programing efficiency. The computer language used is Programing Language/One (PL/1) because it adapts readily to…

Libraries should resist the temptation to relinquish to computing centers the burden of looking after the university's digital data record resources for a growing volume of intellectually important material will arrive at the university on digital data tapes. If the user must arrange for access to this material outside the library, he will be…

The development of machine or computer applications for the arrangement, storage, retrieval, and display of literature references or classification schedules, vocabularies, and indexes used with the Universal Decimal Classification (UDC) System as an access point is reviewed. Activities of the Subcommittee on Mechanization of the UDC Central…
