The Information Flow System is a large-scale information retrieval system developed for processing of Du Pont information files. As currently implemented, the system stores and retrieves information on company technical reports. Extensions of the system for handling chemical structure information and on-line processing are also discussed. (3…

Retrospective search of large data bases requires development of special techniques for automatic compression of data and minimization of the number of input-output operations to the computer files. The computer program should require a relatively small amount of internal memory. This paper describes the structure of such a program. (9 references)…

Advantages of the Berkeley Mass Storage System (MSS) for information retrieval other than its size are: high serial-read rate, archival data storage; and random-access capability. By use of this device, the search cost in an SDI system based on the Nuclear Science Abstracts" data base was reduced by 20 percent. (6 references) (Author/NH)

The author suggests that informative abstracts be published with articles in this magazine so that readers may glean their contents in a fraction of the normal reading time. (Author)

Microfiche storage and computer-assistance to produce multilingual indexes at the United Nations Headquarters Library are described. (Author/NH)

Automated operations simplify billing, inventory control, and ordering of scientific items. (Editor)

Delineated in this bibliography are the characteristics of a number of retrospective bibliographies in one major division of scholarship--the social sciences--in an attempt to identify and sort out the various purposes toward which works in this format appear to be directed. (36 references) (Author)

An account of the rapid growth of a relatively new area of knowledge, and some of the problems in information storage and retrieval involved are presented. (4 references) (Author)

Recommendations are made to improve school district buying methods. (Author/MF)

Some avenues of relief to the book space problem via in-house practices are presented in this paper, all of which have been attempted in some library at some time, but they are only stop-gap measures. The only permanent solution is construction of additional space. (NH)

This discussion of the general principles of structure and construction of numeric databases introduces the concept of data points, their relationship to each other, and their storage in a nonredundant way. The collection of numeric data and their integration into the database structure are explained. Eight references are cited. (EJS)

Discusses developments in the application of computer and microform technologies to the storage and management of large map collections, including online cataloging systems, digital databases, videodiscs, microfilm, and the role of map librarians. A bibliography lists more than 70 sources. (FM)

Describes floppy disk information storage systems and discusses capabilities and advantages of floppy disks for microcomputer users. The functions of disk operating systems (DOS) are reviewed and the effect of DOS formats on the choice of an appropriate disk drive system is outlined. (JL)
