Abstract
Describes the Mercury project, at Carnegie Mellon Univ. Library, Pennsylvania, aimed at extending the scope of the OPAC to include other functions and services: access to full text and other online databases. The collection of databases (e.g. INSPEC, IBI/INFORM) forms the Library Information Systems (LIS2) and is accessible via a common user interface. Describes the distributed computer architecture of the Mercury electronic library with particular note of the document delivery service built into the system and designed to produce electronic documents in ASCII and bitmapped page image format, and in hardcopy format using electronic mail and print services. Pays particular attention to the principles underlying the design of the user interface and gives examples of the UNIX/Motif and VT100 search screens
