Describes the advantages of using variable length equifrequent fragments as the language elements for compression coding of large data bases. (Author)

Described is a storage and retrieval system developed for a pharmaceutical firm for internal document control. There is a thesaurus and four data files. Two important features include coordinate indexing using roles and links as well as the use of Wiswesser Line Notation for storing compounds. (3 references) (Author/SJ)

A brief history of bibliographic activities of the U.S. Geological Survey, including development of a computerized publishing system is given. Also described is the design of the bibliographic search system, application of the Generalized Information Processing System (GIPSY) to storage and retrieval of earth sciences literature, and preliminary…

The Clinical Documentation Section of Schering Corporation's Medical Information Center has developed an automated document storage and retrieval system capable of generating indexes to all documents in the system, summaries, and reports for management by computer. (MF)

The authors envision the library of the future as part of a large network of dedicated computers, each with specialized data bases and inter-computer communications for accessing other data bases. (4 references) (Author)

Highlights the advantages of using holography for information storage, character recognition, file security systems, and other applications. (FM)

Conversion of the Chemical Abstract Service scientific literature data base from Standard Distribution Format to a center-oriented file format, STF, is described. A tape file format is described in which variable length logical records, possibly longer than the blocksize, may be stored safely. (7 references) (Author/NH)

The authors advocate a systematic procedure involving the identification of: fixed parameters, variable options for each variable parameter, factors affecting a choice among available options, factors affected by a choice among available options, and the optimum sequence in which decisions should be made during the design process. (Author/MF)

The main conclusions are: the human factor appears to be the main variable in all components of an information retrieval system; length of indexes affects performance considerably more than indexing languages; question analysis and search strategies affect performance to a great extent - as much, if not more than indexing. (Author/MF)

Describes the utility and applications of information retrieval thesauri and the development of the thesaurus for the DISCLOSURE data base. (PF)

False drops occur in a system of random superimposed coding for edge-notched, punched, and feature cards. Formulae for the false dropping fraction are derived, and figures and tables are given for the calculated values in the most popular scheme. (Author/LS)

A record format and file structure for searching and editing of large textual files have been designed within the 3RIP project. This document describes: (1) general characteristics of the system; (2) implementation of the system on a DEC 10 computer in the programming language, BLISS; (3) external record format; (4) internal format; and (5) file…

A five-year development program plan was drawn up for the Defense Documentation Center (DDC). This report presents in summary form the results of various surveys and reviews performed in selected areas of micrographics to support the efforts of the program's planners. Exhibits of supporting documentation are presented, together with a discussion…

The paper examines several ideas for information handling implemented with new technologies that suggest directions for future development. These are grouped under the topic headings: Handling Large Data Banks, Providing Personalized Information Packages, Providing Information Specialist Services, and Expanding Man-Machine Interaction. Guides in…
