Abstract

The social sciences documentation centre (CDSH) of the French National Research Centre initiated the publication in 1988 of a psychology periodicals catalogue, Catalogue thématiques des revues de psychologie. Discusses the problems involved in setting up such a catalogue, with specific reference to deciding how a printed source can best complement its parent on-line data base: in this case, CDSH's PSYSIS. The decision to produce the catalogue has been largely precipitated by low uptake of the data base. Considerable attention has been given to delimiting coverage (French and foreign specialist periodicals, multi-disciplinary periodicals); defining descriptors (involving decisions about who the periodical is aimed at); and what information to include under each entry. The main problems, still to be solved, concern lack of adequate software (only a relational data base would be fully satisfactory); and inadequate information about user requirements from hard copy material as opposed to on-line data bases. The results of this preliminary evaluation, albeit tentative, are of considerable relevance to the delopment of strategies for diffusing information on scientific periodicals in general.

Abstract

Account of the preliminary stages in the Bibliothèque National project to produce data from the national bibliography, the Bibliographie de France, on CD-ROM. The pilot disc was produced in collaboration with the British Library, using software developed by Online Computers, and tested out in 60 establishments in 1988. Results of this experiment showed up problems in installation, and user dissatisfaction with the indexing system, formats, headings, and instruction manual. Overall, however, user feedback indicated a good market for CD-ROM, as a complement to other sources of bibliographical data. The 1st full edition, with 380.000 records covering 1975-89, was produced in May 89, and a 2nd edition is scheduled for Oct 89. Discussions are currently in hand to develop European standards for CD-ROM, to be used by all national libraries.

Abstract

Report of a study comparing 2 methods of indexing: LEXINET, a computerised system for indexing titles and summaries only; and manual indexing of full texts, using the thesaurus developed by French Electricity (EDF). Both systems were applied to a collection of approximately 2.000 documents on artifical intelligence from the EDF data base. The results were then analysed to compare quantitative performance (number and range of terms) and qualitative performance (ambiguity of terms, specificity, variability, consistency). Overall, neither system proved ideal: LEXINET was deficient as regards lack of accessibility and excessive ambiguity; while the manual system gave rise to an over-wide variation of terms. The ideal system would appear to be a combination of automatic and manual systems, on the evidence produced here.
