Cassis/CD-ROM -- A project report

Abstract

The article describes the development of the classification and Search Support Information System (CASSIS), which is an on-line patent information data service provided by the U.S. Patent and Trademark Office to its network of Patent Depository Libraries (PDLs). The initial success of the system in the early 1980s was so great that its rapidly increasing cost forced some curtailment of its expansion. In 1987 a pilot project was undertaken to determine whether CD-ROM supplied to the PDLs could substitute for some parts of the on-line service. This has proved successful in reducing the cost of the on-line service and further expansion of CD-ROM use to all PDLs is planned in 1989.
