Describes an online library catalog in which bibliographic references have been compiled by simply transcribing the descriptive data found on the title page and elsewhere on the documents, and discusses the wider implications of the use of natural language descriptions without modifications. Eleven references are listed. (FM)

Considers the implications of possible policy initiatives in the United States in light of Swedish experience in dealing with the privacy of computerized records. (CWM)

Examines through a series of mathematical models (theorems, descriptions, and examples), properties and operations on inverted files, which are used in an information retrieval system based on thesaurus with weighted descriptors. (CWM)

Analyzes the use of weights to denote a query representation and/or the indexing of a document as a generalization of a Boolean retrieval system. Criteria are given for the functions used to evaluate the relevance of the records to a specific query and a new evaluation approach is suggested. (CWM)

Presents a new method of document retrieval based on the fundamental operations of fuzzy set theory. Basic notions are introduced. Then the syntax and semantics of the proposed language for document retrieval is given, and an algorithm allocating documents to particular queries is described and its properties are discussed.
