A subjective evaluation comparing the National Aeronautics and Space Administration RECON and National Library of Medicine ELHILL 2 on-line information retrieval systems is presented as they relate to the delivery of a major service dealing with a collection of toxicological bibliographic references (TOXLINE). Comparisons of file structure, response time, command language, system environment, and other relevant features are made based upon actual experience with both systems.
