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)

Reports that the United States Geological Survey has recently prepared computer print-outs of the rock-stratigraphic names in good usage in published references in the United States, using the standard stratigraphic code of the American Association of Petroleum Geologists. A sample of the print-out is provided with explanatory notes. (JR)

Reviews computer storage devices designed to provide additional memory for microcomputers--chips, floppy disks, hard disks, optical disks--and describes how secondary storage is used (file transfer, formatting, ingredients of incompatibility); disk/controller/software triplet; magnetic tape backup; storage volatility; disk emulator; and…

Relates office automation to its application in libraries, discussing computer software packages for microcomputers performing tasks involved in word processing, accounting, statistical analysis, electronic filing cabinets, and electronic mail systems. (EJS)

Reviews the special requirements of a bibliographic database, and shows how they are met in the DOBIS-LIBIS (Dortmund Library System-Leuven Library System) system. Full authority file control over the indexes to the database is discussed, and the DOBIS-LIBIS system is described in detail. References are included. (Author/BK)

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…

Introduces some algorithmic methods, for which no pre-editing is necessary, for automatically "lemmatising" raw text (changing raw text to an equivalent version in which all inflected words are artificially transformed to their dictionary look-up form). The results of a study of these methods, which used a German Text, are also given. (KM)

STARTING FROM A MODEL OF CONTEMPORARY MECHANIZED RETRIEVAL SYSTEMS AND THE CHARACTERISTICS OF INDEXING LANGUAGES USED THEREIN, THE AUTHORS DEVELOP A RATIONAL BASIS FOR USE OF THE UNIVERSAL DECIMAL CLASSIFICATION (UDC) IN THIS CONTEXT. PRACTICAL DESIGN CONSIDERATIONS FOR THE USE OF UDC IN A MECHANIZED RETRIEVAL SYSTEM ARE DISCUSSED. EXAMPLES ARE…

A novel text analysis and characterization method involves the generation from text samples of sets of variable-length character strings. These sets are intermediate in number between the character set and the total number of words in a data base; their distribution is less disparate than those of either characters or words. The size of the sets…

In contrast to conventional information storage and retrieval systems in which a body of knowledge is thought of as an indexed codex of documents to which access is obtained by an appropriately indexed query, this interdisciplinary study aims at an understanding of what is "knowledge" as distinct from a "data file," how this knowledge is acquired,…

The manual describes the generalized information retrieval Query System and provides procedures and instructions for creating the data base, loading a time-sharing computer, and retrieving specified information via a remote terminal. Using the system, an analyst may load into computer storage, in a pre-defined format, information or data and then…

The Air Force Logistics Command (AFLC) is revising and enhancing its data-processing capabilities with the development of a large-scale, multi-site, on-line, integrated data base information system known as the Advanced Logistics System (ALS). A data integrity program is to be built around a Data Base Manager (DBM), an individual or a group of…

The National Library of Medicine maintains a computerized analysis and retrieval system and administers various programs for collecting, publishing, disseminating, and exchanging medical health information. A major use of the library's computer is to prepare bibliographies of biomedical subjects requested by medical schools, researchers,…

Discusses tax preparation and planning programs for microcomputers, including how programs save time and money, how they may or may not perform calculations accurately, how they compare to services offered by professional tax preparers, and the deduction of software costs. Ten tax programs are listed and described. (MBR)
