A method of constructing a check digit for nonconventional chemical codes is described. (5 references) (Author)

These guidelines provide a basis for determining the content and extent of documentation for computer programs and automated data systems. Content descriptions of ten document types plus examples of how management can determine when to use the various types are included. The documents described are (1) functional requirements documents, (2) data…

Information and documentation have constituted one of the more fruitful fields for early applications of computer typesetting. This review pays particular attention to the reasons this is so, and to some of the major systems now in operation. (31 references) (Author/NH)

UNESCO, in cooperation with several other organizations, has produced a manual, the scope and purpose of which has been to define, for most types of scientific and technical literature, a set of data elements which will constitute an adequate bibliographic citation, and to define the representation of these data elements as they should appear in a…

Testimony given by Dr. John Rothman, Manager of Information Services, New York Times, before the General Subcommittee on Education ... describes the information retrieval system of the New York Times. He describes how the system will process material efficiently and economically, store it securely and in proper order, and make it available via…

The problem of quality service assurance in a computer networking environment is addressed. In the absence of any direct, well-defined, quantitative measure of service quality and reliability, error collection and analysis is the only basis for service quality control. Therefore, mechanisms are described which facilitate reporting of operational…

The Library Information System Time-Sharing (LISTS) experiment was based on three innovations in data processing technology: (1) the advent of computer time-sharing on third-generation machines, (2) the development of general-purpose file-management software and (3) the introduction of large, library-oriented data bases. The main body of the…

Discusses the 1995 OCLC/NCSA Metadata Workshop that met to define a standard set of data elements for describing network-accessible information resources. These document data elements had to be simple enough for authors and publishers to use, to facilitate discovery and retrieval, and to be useful as a basis for descriptive cataloging. (JKP)

Response time in large, inverted file document retrieval systems is determined by time required to access files of document identifiers on disk and process a Boolean search request. A specialized computer system has been devised that can perform a complicated sample search involving 70 terms and over 60,000 document references 12 to 60 times…

THE PURPOSE OF THE PROJECT WAS TO IDENTIFY AND DEFINE THE PARAMETERS OF AN ECONOMICAL AND PRACTICAL INFORMATION SYSTEM FOR THE U.S. ARMY ENGINEER RESEARCH AND DEVELOPMENT LABORATORIES. THE PROGRAM INCLUDED FOUR PHASES--(1) DATA REQUIREMENTS DEFINITION, (2) COST ANALYSIS AND SYSTEM DEFINITION, (3) HARDWARE SELECTION, SYSTEM TEST AND EVALUATION, AND…

A description of the system used by Space Documentation Service (SDS) to disseminate combined and accumulated knowledge, as widely as possible, throughout Europe is given. The RECON network, with the full support of NASA, has gradually been extended so that centers in Member States, may, by installing their own terminals, have direct access to the…

THIS VOLUME PRESENTS THE RESULTS OF A NINE-MONTH TEST OF A PROTOTYPE SELECTIVE DISSEMINATION OF INFORMATION (SDI) SYSTEM DEVELOPED FOR THE ARMY TECHNICAL LIBRARIES. DURING THE PILOT TEST ONE THOUSAND DOCUMENTS WERE CATALOGED, INDEXED, AND DISSEMINATED TO TWENTY-FIVE SCIENTIFIC AND TECHNICAL PERSONNEL. MATCHING OF THE INTEREST PROFILES OF THESE…

The new data retrieval system for the social sciences which has recently been installed in the UNESCO Secretariat in Paris is described in this comprehensive report. The computerized system is designed to facilitate the existing storage systems in the circulation of information, data retrieval, and indexing services. Basically, this report…
