An unprecedented amount of information encompassing almost every facet of human activities across the world is generated daily in the form of zeros and ones, and that is often the only form in which such information is recorded. A good fraction of this information needs to be preserved for periods of time ranging from a few years to centuries.…

Explains the function and operation of the Chemical Registry System operated by Chemical Abstracts Service (CAS). (CP)

Explores the use of analog optical disks as a practical, cost effective means of building picture databases. Questions that should be asked to determine whether optical disk is a suitable picture storage alternative for a particular application are identified and three implementation issues--imaging, indexing, and integrating--are discussed. (CLB)

Efficient search of items in a store of information, such as books in a library, abstracts of articles, information in a computer data bank or the like, requires that the items most closely connected in content be close together, in order that a person looking for some particular information may concentrate his search on as small a part of the…

This report describes Phase 1 of a research project with the over-all objective of exploring the applicability of automatic methods in the indexing of drug information appearing in English natural language text. Two major phases of the research have been completed: (1) development of the automatic indexing method and its implementation on the test…

This report describes the searching methods and the search program for the automatic indexing method which was developed and implemented in an earlie r phase of the project. The indexing method generates index tags automatically from English language text and creates a machine searchable file of index records for the document being processed.…

This book is the final report of a two year research project. It offers a thorough discussion of the potentialities and limitations of computers for library application. A general treatment is presented of the whole library as it may be in the future. Emphasis is given to the usefulness of the computer as a device for ease of transmission of…

AREAS INVESTIGATED INCLUDE SLOW MEMORY DATA STORAGE, THE PROBLEM OF DECODING FROM AN INDEX TO A SLOW MEMORY ADDRESS, THE STRUCTURE OF DATA LISTS AND DATA LIST OPERATORS, COMMUNICATIONS BETWEEN THE HUMAN USER AND THE SYSTEM, PROCESSING OF RETRIEVAL REQUESTS, AND THE USER'S CONTROL OVER THE RETURN OF INFORMATION RETRIEVED. LINEAR, LINKED AND…

This report is a revision and expansion of an earlier research report that described the design of the University of Guelph's documentation system for the organization of government publications within university libraries. The design of the Guelph document system represents a deliberate departure from cataloging and classification theory and…

Improvements in the technology associated with the information sciences will have their primary potential impact on the distribution of costs, information flow level, information availability, and use among information channels. This improvement implied not only a capability to perform a given function, but a lower cost. For example, the trend…

E-learning leads to evolutions in the way of designing a course. Diffused through the web, the course content cannot be the direct transcription of a face to face course content. A course can be seen as an organization in which different actors are involved. These actors produce documents, information and knowledge that they often share. We…
