Abstract
The availability of two full text data bases in the clinical medical journal literature, MEDIS from Mead Data Central and CCML from BRS Information Technologies, provided an opportunity to compare the efficacy of the full text to the traditional, indexed system, MEDLINE for retrieval effectiveness. 100 searches were solicited from an academic health sciences library and the request were searched on all 3 data bases. The results were compared and preliminary analysis suggests that the full text data bases retrieve a greater number of relevant citations and MEDLINE achieves higher precision.
