Describes a study that compared retrieval obtained by searching hardcopy and online indexes. Measures of comparison were recall and precision, user preferences, and the amount of effort required to complete the search. The findings indicate that neither method offers an overall advantage and suggest that both search modes should be maintained. (12…

Describes the development of computer-based searching methods to support literature-based discoveries in medical literature through a replication of the discovery of a connection between Raynaud's disease and dietary fish oil. Topics include the logic of literature-based discovery, information retrieval methods for text analysis, and statistics…

Discusses the shift of information access from a data-centered to a user-centered model and describes the Daltext system, a prototype user-centered information system that allows the user to determine how the data will be viewed (i.e., within a datastream model, a set model, a relational model, and/or a hierarchical model). (Contains 30…

Discussion of the use of dynamic data resources, such as Internet LISTSERVs or Usenet newsgroups, focuses on an experiment using an automated filtering system with Usenet newsgroups. Highlights include user satisfaction, based on retrieval size, data sources, and user interface and the need for some human mediation. (Contains two references.) (LRW)

Discusses ways to locate information on the Internet. Highlights include LISTSERVs; files to download, including text, graphics, software, sounds, and animations through Archie; locating files on a Gopher via Veronica; the World Wide Web; and electronic mail addresses. (LRW)

Discussion of users and information retrieval systems highlights a study that investigated the representation of users' knowledge by examining their names for objects and concepts, agreement on names, the Library of Congress Subject Headings representation for similar objects and concepts, and measurement of the similarity between these…

Two teachers and seven media specialists from five school districts in Muskingum County (Ohio) had three weeks to write a proposal for a library automation grant.

Highlights include elements of situatedness, with examples; the mapping of individual searches; and users' goals and stopping behavior. (Author/LRW)

Discusses user-centered thinking and lessons from reader-centered theory. Reviews findings from studies by literary theorists on user-centered approaches to information and uses these findings to support and offer two analogies: (1) an analogy between reader and library user; and (2) an analogy between information and the library.
