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…

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)

In order to compare effects of input processing on information retrieval in three databases, 25 articles from a specific journal were examined. Tables and Venn diagrams show retrieval results from different manual and computer searches. The relation between document surrogates and subject matter of the documents is discussed. (SW)

Discussion of Web databases, or search engines for the Internet, presents a series of questions that can be used to analyze these tools based on library literature. Six search engines are analyzed; collection methods, indexing, and abstracting are compared; and a proposal for a future ideal Web database is included. (Author/LRW)

Applies a prefix trie index, or trie hashing, to the problem of providing fast search times, fast load times, and fast update properties in a bibliographic or full-text retrieval system with inverted files. Statistics are given for a test database consisting of an online catalog at the University of Western Ontario. (Author/LRW)

Examines strengths and weaknesses of organizational systems developed to organize and access electronic resources available via the Internet. Highlights include library online catalogs; cataloging rules and MARC records; text encoding initiative (TEI) headers; the Internet union catalog; browsing lists; robot-generated indexes; a core data set of…

Discussion of MEDLINE document indexing focuses on a study that assessed the use of free text, Medical Subject Headings (MeSH), and a variety of combination retrieval strategies. Prior research involving free text and controlled vocabularies is reviewed, and results of the study indicate that MeSH does have an important role in text retrieval.…

Discussion of the information needs of medical professionals and researchers focuses on the architecture of a Web portal designed to integrate advanced searching and indexing algorithms, an automatic thesaurus, and self-organizing map technologies to provide searchers with fine-grained results. Reports results of evaluation of spider algorithms…

The first article describes characteristics of ephemera, discusses its importance as resource material in library collections, and presents suggestions for providing access to such materials. The second describes the acquisition and treatment of 15 collections of Australian ephemera at the National Library, and the third describes the…

Discusses the status of a pilot project undertaken by the ERIC facility to provide access to education-related statistical tapes. Procedures developed for the identification of sources of such tapes, documentation for the tapes, and the creation of surrogate records for cataloging, indexing, and abstracting are described.
