Discussed is the renewed attention given in the education of engineers to documentation and information. A framework for training in the command of specialized or professional information is presented. The objectives that should be pursued in terms of training for the command of specialized information are described. (KR)

Describes a study which investigated the general patterns and level of applicability of Anglo American Cataloging Rules (AACR2). It is suggested that designers and revisers of AACR2 should reduce the number of rules of very limited applicability levels and enhance the rule contents for application domains to expand the usefulness of AACR2. (SD)

Describes a study that investigated how much information the users of online search services wanted when they had a search conducted. User satisfaction with the results of hypothetical searches in terms of the number of documents retrieved and the precision of the search is examined, and multiattribute decision making is discussed. (40 references)…

Reviews the literature on enhancement of catalog records using table of contents information and reports on a study at San Diego State University that examined the proportion of catalog records in the collection that could be enhanced, the extent of enhancements, and the nature of the information that could be added to notes. (24 references) (EA)

(EAM)

Describes enhancements made to a hypertext information retrieval system at the National Energy Research Supercomputer Center (NERSC) called DFT (Document, Find, and Theseus). The enrichment of DFT's entry vocabulary is described, DFT and other hypertext systems are compared, and problems that occur due to the need for frequent updates are…

Describes the incorporation of textile images into the University of Maryland Historic Textile Database by a computer user rather than a computer expert. Selection of a database management system is discussed, and PICTUREPOWER, a system that integrates photographic quality images with text and numeric information in databases, is described. (three…

Explores the usefulness of the Research Libraries Information Network (RLIN) to humanities scholars. Contends that factors such as inaccessibility of terminals and difficult-to-use interfaces inhibit the utility of the database. Maintains that use of the RLIN should help database managers plan the next generation of information systems. (CFR)
