Introduces this issue, which contains papers from the 1991 Data Compression Conference, and defines data compression. The two primary functions of data compression are described, i.e., storage and communications; types of data using compression technology are discussed; compression methods are explained; and current areas of research are…

The work reported here was performed between 1 June 1967 and 31 May 1968 under Task I of the contract between Chemical Abstracts Service (CAS) and the National Science Foundation (NSF). The objective of this contract was to achieve an operational, integrated, man-machine system for manipulating information about chemical substances. The contract…

The coordinator of information systems at the Library of Congress and his assistant describe the application of computer technology to the library's current automation goals. (AA)

Administrative Terminal Systems (ATS) operations are detailed, the use of ATS for text processing is evaluated in comparison with the IBM Magnetic Tape Selectric Typewriter (MTST), and the importance of the interaction of ATS with computer peripherals is described. (8 references) (Author/NH)

The American Institute of Physics Current Physics Information program offers new products to help scientists and engineers stay up to date, including a computer tape file and microfilm cartridge of selected articles. Later additions will include title, advance abstracts and bibliographic publications. (TS)

Two essential components of the information-logic problem are: (1) choosing some known part of the total information block for parallel review of the entire block and (2) parallel logic processing of a sequence of codes. The described device fulfills these essential components thereby improving information processing and increasing the speed of…

Addresses single-user microcomputer systems and information processing applications normally performed through use of data management, spreadsheet, word processing, business graphics, and communications software. Both hardware and software considerations are included with an emphasis on hardware once appropriate application software-level packages…

Holography is one of the most promising methods now under research for the achievement of high bulk storage with fast random access at a reasonable cost. (Author)

Describes new microcomputer software and hardware which simplify data communications between computer systems. "Dumb" terminal software, programs which enhance a computer's data communications flexibility by means of character translation and data buffering, stand-alone versus integrated systems, and "smart" modems are…

Describes the information processing system employed by Chemical Abstracts Service which utilizes computers to organize material from the data base, convert it to the appropriate type face and format, and photocompose it in a form suitable for conversion to offset printing plates. (GS)

An interactive search and editing system, 3RIP, is being developed at the library of the Royal Institute of Technology in Stockholm for large files of textual and numeric data. A substantial part (on the order of 10-E9 characters) of the primary file of the search system will consist of bibliographic references from a wide range of sources. If the…

The second edition of the directory presents information about the computer services provided to outside customers by commercial concerns, service bureaus, consultants, and educational and research establishments throughout the world. It lists the names, addresses, telephone numbers, and principal officers of institutions and companies, together…

While data processing cannot, as yet, provide automatic translation, computer assistance is valuable for information storage and retrieval in dictionary work, text-related glossaries, and text banks. (CK)

Describes three stages of the automation of information processing systems by combining the concept of the exponential growth of operational capabilities with three characteristics: computational capability, ability to store data, and ability to communicate data. The growth of fiberoptic technology is described as beginning the third stage. (EM)
