Examines design functions of present file organizations in the context of available data storage devices and identifies current developmental trends. (Author/RAA)

Discusses ranking techniques for document retrieval and proposes an evaluation, or filtering, technique that reduces costs and memory usage by early recognition of which documents are likely to be highly ranked. Highlights include index design, ranked query evaluation, reducing the number of accumulators, inverted file structures, and experimental…

The Ohio State University Libraries On-line Remote Catalog Access and Circulation Control System (LCS) began on-line operations with the conversion of one department library in November 1970. By December all 26 libraries had been converted to the automated system and LCS was fully operational one month ahead of schedule. LCS is designed as a…

An analysis of computer-based search services (ISSs) from a system's viewpoint, using a continuous simulation model to reveal growth and stagnation of a typical system is presented, as well as an analysis of decision making for an ISS. (Author/MBR)

Introduction to videodisc and optical disk technology (information storage media which are able to handle word, data, image, and sound) cites articles written about videodisc and optical disk applications, instructional use, videodisc research, and information retrieval. A list of 30 suggested readings and additional information resources are…

This report describes the development and implementation of a prototype system that integrates a microfiche catalog into an online computer system for bibliographic control. Such a system permits the storage of catalog data not yet converted to digital form, data in ideographic form, data for large numbers of little-used records, and data for use…

This bibliography lists 162 unclassified - unlimited reports acquired by DDC, with their abstracts, grouped into five general subject areas: programing (computers), information retrieval, time sharing, graphics, and general applications. The topical arrangement is complemented by four indexes: corporate author/monitoring agency, personal author,…

Presents examples of bibliographic, full-text, and numeric databases. Also discusses how to access these databases online, aids to online retrieval, and several issues and trends (including copyright and downloading, transborder data flow, use of optical disc/videodisc technology, and changing roles in database generation and processing).

This online pilot project demonstrates the feasibility of using the OCLC transaction tapes to create an online catalog, and the utility of the BRS database structure for loading this data and for online searching. It also shows the feasibility of a user-cordial interface for patrons and for staff and provides an opportunity to test many factors…

Discusses the feasibility of individual television film libraries combining film holdings onto optical disks and developing networks that would allow online searching of, access to, and transmission of video images. It is concluded that recent advances in technology would support fast and cost effective image retrieval with no loss in video…

This paper is primarily an annotated listing of criteria for selection of a microcomputer to be used for online information retrieval. The paper was used by the University Library of the Technische Universitat Wien (Vienna, Austria) while preparing to contact computer dealers and to inform them about the library's needs in this specialized area of…

InfoTrac is a laserdisc system that provides local computer-access to Information Access Company's periodical databases and offers libraries an extensive, self-contained reference system. The system, which employs an IBM PC microcomputer, a Hewlett-Packard Thinkjet printer, and a Pioneer videodisc player, provides advantages of online searching at…

The command language features of 11 on-line information retrieval systems are presented in terms of the functional needs of a searcher sitting at a terminal. Functional areas considered are: becoming familiar with the system, receiving help when in trouble, regulating usage, selecting a data base, formulating simple queries, expressing single…

WISE is an on-line interactive information retrieval system designed particularly for bibliographic data bases, but it is potentially useful for any keyword-oriented data base. The WISE user searches a data base by entering and combining keywords that are appropriate to the data base and the subject area of interest. The user can also enter…

The papers and discussions of the 1975 Pacific Region meeting of the Association for Computing Machinery are presented. Topics included (1) the current and emerging state of the art in data management software and hardware, (2) relational systems with particular attention to new developments in systems for relational data bases, (3) advances in…
