Variety-generator approach seeks to reflect the microstructure of data elements in their description for storage and search, and takes advantage of the consistency of statistical characteristics of data elements in homogeneous data bases. (Author)

Software, hardware, procedural, and operational components of the California State University and Colleges systemwide approach to library automation are reviewed with specific emphasis on the time periods involved, the phasing of implementation, and finally, the costs and benefits anticipated from this project. (Author)

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)

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.

The extreme flexibility of the MARC format coupled with the simplicity of a batch-oriented processing system centered around a sequential master file has enabled the University of California, Berkeley, library to gradually build an unusually large serials data base in support of both technical and public services. (Author)

Gives an overview of MEDLARS II as an example of a major bibliographic processing system that supports on-line access to a number of very large files, has efficient throughput, and is operated on a single large-scale computer. (Author/PF)

Discusses database structure, concepts, and management systems in library settings and describes the Comprehensive Automated Learning Resource System (CALS). This system was developed by NILRC to meet the needs of libraries which incorporate print and audiovisual materials in their collections. (RAA)

An experiment in manipulating machine-readable library records for use in subject searching indicated that such programs would be useful to extend service outside a single library location. (Author/PF)

A regionally organized program for serials bibliography is proposed because of the large volume of complex data needing control and the many purposes to which the data can be put in support of regional or local needs. (2 references) (Author)

Describes a user-interactive system for the selection and display of pictorial information stored on microfiche cards in a computer-controlled viewer. (Author)

A description of existing U.S. library networks, the resources available from them, and some technical and policy issues. (LS)

Explains how a multipurpose bibliographic/MARC data base of machine-readable data files (MRDF), created according to the MARC II record format, was conceived, and how much an information resource would benefit the general user and professional librarian. (Author/CWM)

Describes the local off-line data base at North Carolina State University, which is updated from OCLC archive tapes, and reviews the processing required to make this data useful for maintaining the data base and providing some ancillary services. (CWM)

Reviews problem areas identified in the processing of OCLC MARC Subscription Service tapes, commonly known as the archive tapes, and explains the Yale University methods for processing these tapes through their editing project and notation system. (CWM)

Presents MARC database statistics for use in planning and processing files, selection of subsets, and estimating file growth rates. Statistics are provided on record length, field tag occurrence, data element length per field tag, and distribution of records by Dewey Decimal Division and Library of Congress class code.
