In response to the rapid development of digital libraries over the past decade, researchers have focused on the use of metadata as an effective means to support resource discovery within online repositories. With the increasing involvement of libraries in digitization projects and the growing number of institutional repositories, it is anticipated…

When documentary material is indexed by a mechanized classification system, and the results judged by trained professionals, the number of documents in disagreement, after suitable adjustment, defines the error rate of the system. In a test case disagreement was 22 percent and, of this 22 percent, the computer correctly identified two-thirds of…

It seems, at times, that a frantic race persists to ensure that a child, in the crucial learning stages of early elementary education, acquires the appropriate reading level before he or she "gets behind." Though there are obvious issues with branding a book "Grade Level One" or "Reading Level 2.2," it is nevertheless…

This article attempts to offer an overview of the current changes that are being experienced in the management of audio-visual documentation and those that can be forecast in the future as a result of the migration from analogue to digital information. For this purpose the documentary chain will be used as a basis to analyse individually the tasks…

An indexing system to 1850 documents on library automation, systems studies in libraries, and indexing systems was developed for use in instruction and research. The indexing system consists of an on-line searched coordinate index, a printed coordinate index, a subject authority list, an abstract bulletin containing the 1850 documents in the…

Reports a computer assisted index emphasizing expanded subject access to the reference collection of the Iowa State University Library. The index displays abbreviated length records and complements existing catalogs. Limitations of subject access and a system for assigning subject descriptors are discussed. (Author/RAA)

Variety-generator approach seeks to reflect the microstructure of data elements in their description for storage and search, and takes advantage of the consistency of statistical characteristics of data elements in homogeneous data bases. (Author)

Comments are given on: the 18th edition of the Decimal Classification, the MARC Automated Serials System (MASS) project, and the Cataloging and Indexing Group's survey of catalog use. (11 references) (NH)

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)

An access method for bibliographic records that combines features of the search key approach and the inverted file approach. Permits extension of search key technique to large files. (Author/LS)

Reviews selected research on content-enriched access (including information components such as tables of contents and indexes) in information retrieval systems. It is concluded that well-selected content components and full-text materials in electronic systems must be linked with improved search methodologies, better interfaces, and greater…

In times when the total volume of information is proliferating and information users are demanding greater access and faster response, the librarian is likely to turn to the computer for assistance. Modern computers can provide fast, accurate operations with an enormous capacity for bibliographic data, and they can be accessed through on-line,…

Describes a project that experimented with using a NeXT computer as a cataloger's workstation. The use of Digital Librarian software to access the text of "Anglo-American Cataloging Rules" (AACR) on magneto-optical disk is discussed, and suggestions for future developments are made. (four references) (LRW)

In this third of five course installments, the role of Library of Congress in providing improved subject access and weaknesses or defects of Library of Congress Subject Headings (LCSH) are discussed. Reflections of six practioners and researcher/teachers on long term use of LCSH and the MARC bibliographic record are presented. (EJS)

Describes procedures followed in the use of a microcomputer to develop an index to a collection of vocal sheet music at the Music Library of the University of Colorado. Indexes generated using four fields--title, composer's last name, lyricist's last name, and first line--are noted. (EJS)
