Provides an overview of indexing in database management systems to provide librarians with more understanding of the possibilities and limitations of current information systems. Sequential, direct, indexed sequential, and virtual sequential file accessing methods are explained, and various binary tree structures are described. (EAM)

Discusses traditional information retrieval through indexing terms and describes a document storage and retrieval system based on structured information, where the SGML document is transformed into Grove (Graph Representation of Property Values) and stored at an element level by an object-oriented database management system. Also discusses query…

Describes a microcomputer-assisted method of using the commercial dBase III software package for the management of a personal bibliographic storage and retrieval system. This system provides users with a systematic way of keeping, for rapid retrieval, references to papers or documents previously read. (Author/CLB)

Discussion of digital imaging technology focuses on its potential use for preservation of library materials. Topics addressed include converting microfilm to digital; the high cost of conversion from paper or microfilm; quality; indexing; database management issues; incompatibility among imaging systems; longevity; cooperative pilot projects; and…

Describes the National Aeronautics and Space Administration (NASA) Lexical Dictionary (NLD), a machine-aided indexing system used online at the NASA Center for AeroSpace Information (CASI). The functions of NLD system components are described in detail, and production and quality benefits resulting from machine-aided indexing at CASI are…

Presents description of the Generalized Automatic Text Organization and Retrieval system (GATOR), a database system that indexes and retrieves information from machine-readable texts such as interviews and case histories. Qualitative and quantitative analyses are discussed, and integrating GATOR with standard statistical packages is described.…

Describes an information retrieval system developed at Bell Laboratories to create and maintain a variety of different but interrelated databases, and to provide controlled access to these databases. The components discussed include the interfaces, indexing rules, display languages, response time, and updating procedures of the system. (6 notes…

Discusses criteria for evaluating microcomputer database management systems (DBMS) used for storage and retrieval of bibliographic data. Two popular types of microcomputer DBMS--file management systems and relational database management systems--are evaluated with respect to these criteria. (Author/MBR)

This interview with Bertrum MacDonald discusses the decisions that determined the character of a national bibliography on science and technology in Canadian history. Topics discussed include the scope of the project; classification and indexing decisions; the database management system used; unexpected problems; and predicted usage of the…

Provides a checklist of considerations for installing document image processing with an electronic document management system. Other topics include scanning; indexing; the image file life cycle; benefits of imaging; document-driven workflow; and planning for workplace changes like postsorting, creating a scanning room, redeveloping job tasks and…

BUDCAT/MEDIT software mounted on Digital Equipment Corporation VAX equipment at the University of Saskatchewan Library has proven to be effective for rapidly creating a database for the collection of government publications. Simplified records and the ease of using this system have made it possible to create a database with only minimal additional…

Looks at some of the problems of finding digital geographic data in the electronic information infrastructure. Discusses the literature describing trends in organizing information resources in an electronic environment, including spatial information cataloging systems; the paper-based system from which they arose; and new Internet finding tools.…

Describes collaboration between the University of California at Berkeley and four other universities to develop interoperable servers containing each participant's Computer Science Technical Reports and to make them available over the Internet using standard protocols. The proposed library architecture, approaches to indexing and retrieval, and…
