Discusses the evolution of standards for bar codes (series of printed lines and spaces that represent numbers, symbols, and/or letters of alphabet) and describes the two types most frequently adopted by libraries--Code-A-Bar and CODE 39. Format of the codes is illustrated. Six references and definitions of terminology are appended. (EJS)

On-line circulation control systems are operating in three University libraries and in at least five public library systems in Australia. These systems fall into three types; those based on punched cards, those based on keyboard entry, and those using light pens and bar-coded labels. (Author)

In 1972-73 the University of Guelph Library used machine readable files of its collections to take inventory. A book detection system was also installed which reduced losses to .5 percent for the year. (Author/AP)

A survey was conducted of libraries with computer-based circulation departments asking for a description of the equipment in use and an evaluation of the system. Equipment manufacturers were contacted to obtain complete descriptions of the capabilities and characteristics of various data collection systems. (Author)

Outlines innovations in library tools made possible by use of computer output microfilm. (PF)

The impact of a bibliographic retrieval/card production system, such as the Ohio College Library Center (OCLC), on the cataloging procedures of the large academic library is examined. (11 references) (Author/RS)

The Ad Hoc Discussion Group on Serials formed on June 26, 1973, is attempting to foster cooperation and coordination in the generation and maintenance of machine-readable union files of serials. (Author/RS)

Books are automatically retrieved -- and filed -- at the Health Sciences Library of Ohio State University. (Author)

After emphasizing the advantages of an automated library network, the author describes the stages which led to the establishment of the master plan for an automated network for Austrian libraries and to the adoption of a format suited to the specific needs of these libraries.

Described is the file organization and design of an on-line catalog suitable for automation of one million books. A method of virtual hash addressing allows rapid search of the indexes to the catalog file. Storage of textual material in a compressed form allows considerable reduction in storage costs.

Systems analysis, as a prelude to library automation, is an inevitable commonplace fact of life in libraries. Maturation of library automation and the systems analysis which precedes its implementation is observed in this article. (55 references) (Author/TW)

Comments are given on: the 18th edition of the Decimal Classification, the MARC Automated Serials System (MASS) project, and the Cataloging and Indexing Group's survey of catalog use. (11 references) (NH)

The direct-chaining technique of hash coding is generalized in a manner that is useful for storing records on the basis of non-unique search keys. Two hash functions are used, a process implying a tree structure. Two models, one involving unique and the other non-unique keys, are presented. (7 references) (Author/KE)

An on-line serials control system with particular emphasis on storage and maintenance concepts is described. The system allows real-time display and updating of all elements of the file. (6 references) (Author)

The MARC system which is available today must be the forerunner of a more comprehensive, interactive system of shared bibliographic information. (Author/NH)
