British Library, Science Reference & Information Service, 25 Southampton Buildings, Chancery, Lane, London WC2A 1AW, UK

A companson is made of the relevance and quality of 24 SDI profiles on the INSPEC database, before and after the introduction of searchable abstract words. It was found that there was an approximately 40% increase in both the total number of hits and the number of relevant hits, with no statistically significant changes in relevance. It is suggested that when good abstracts are wntten, indexing terms may be unnecessary.
