    Abstract
    Since Dec 86, the Australian Defence Force Academy (ADFA) library has been enriching bibliographic records by adding terms from either the contents pages or indexes of books. 40.000 records are now enriched, representing about 25% coverage of the ADFA database of 210.000 titles. Evaluates the retrieval effectiveness of the enriched data in an OPAC, in comparison with title and LCSH, using 90 topics from 6 different subject areas
