An experimental program using two magnetic tape data bases from Chemical Abstracting Service ("CT," and "CA Condensates") at the University of California at Riverside (UCR) is reported. Cost studies are based entirely upon the University's ability to purchase the tapes and the Computing Center's interest in underwriting part of the project. Sophisticated cost analysis and possible income were not considered to be major objectives of the project; thus, some study information is somewhat superficial and poorly documented. The basic goal was service to the UCR campus clientele. Some of the problems are a result of resistance from within the organization both by users through fear of failure and expense and by the administration in their inability to provide adequate staff and funding. In spite of these problems, a working system for both "CA" and "CT" tape services has been developed, and some experience and expertise in profiling and teaching methods, and a growing number of satisfied users have been gained.
