Title
PRECIS for subject access in a national audiovisual information system
Source
Canadian library journal. 43(1986), S.177-184
Year
1986
Abstract
The first opportunity to assess a largescale application of the PRECIS indexing system in North America came with its adoption by the National Film Board of Canada as the method of subject access to a national information system for Canadian audiovisual materials. The authors provide an overview of PRECIS use by this automated bibliographic service - the reasons for its choice, the challenge involved in the subject analysis and indexing of audiovisual documents, the methodology and software used to process PRECIS records, the resulting catalogue subject indexes and user reaction
