Discusses the problem of duplicate citations resulting from file overlaps in multidatabase searching and shows that such duplicates could be identified automatically and eliminated by a host computer as a complementary service to online retrieval. Steps involved in the realization of this service are described, and 11 references are listed. (RBF)

Describes student-produced simulations of four online services--Lockheed DIALOG, BLAISE MARC, BLAISE MEDLINE, and SDC. Intended to teach keyboard use, basic commands, and more advanced techniques, the programs are written in BASIC and transferable to a wide range of computers. Several sample displays and seven references are provided. (RBF)

Surveys the technology of database software and hardware, describing some of the principal issues related to the user's view of data, sharing, concurrent access, security, and integrity. (JN)

Cherry Creek (Colorado) and Los Angeles (California) school districts are using microcomputers linked to central computers to process student data. (Author)

Examines the development and current status of research on personal information systems, i.e., those systems where an individual collects, annotates, and stores bibliographic information according to his own needs and preferences. Effects of computer-based dissemination services on the growth and management of these systems are discussed. Included…

Examines the assumptions which underlie the design of SDI systems with respect to context of use, activities supported by SDI, and characteristics which make documents useful. Relates these assumptions to the failure of SDI to gain widespread acceptance among scientific information users. A 43-item reference list is included. (JL)

Describes a dialog-program which uses basic statements available on a WANG 2200T version connected to a floppy-diskette to cross-reference a given set of keywords, author names, journal names, and specified reference numbers. Special program features are described and two references are listed. (Author/RBF)

Describes an indexing technique based on overlapping word fragments as reference strings that are linked in a directed graph structure which makes possible exact match-, partial match-, and masked-partial match-retrieval and indicates search strategies for each case. Eight figures, two tables, and nine references are provided. (RBF)

Recounts the development of a slide storage and retrieval system at the Philip Morris Research Center in Richmond, Virginia and describes the methods used to classify and access slides in the collection. A reference list and three appendices accompany the text. (JL)

Attractive features of the videodisc, a storage medium of digital and visual information, include large storage capacity, low cost, rapid access, and ease of duplication. Widespread adoption of the videodisc will be determined by availability of appropriate software and funding, and public demand and perceptions about its advantages over other…

Presents a survey of UNESCO and other international programs in the field of training information users, outlining problems in connection with types of information users and reasons why information is not always sought. (Author/CWM)

Discusses programed instruction as a technique for teaching the fundamentals of monographic searching on the OCLC database, the method used in developing the instructional text, the series of validation tests conducted, and some suggestions for future research. (Author/FM)

Reports the results of a survey about the teaching of computer programing and online searching of databases taught in American Library Association accredited library schools. (Author/FM)

Originally part of a symposium on educational media for the deaf, the paper reports on the status of the National Media Center for Severely Handicapped Persons. Listed among the six major objectives of the center is the location and retrieval of instructional media materials. (PHR)

Summarizes trends in the dissemination and exchange of geoscience information. Two major themes in 1980 are (1) the growth and development of computerized data bases, and (2) increased cooperation among professional organizations and government agencies. (Author/WB)
