This report is a survey of five on-line retrieval systems that, with one exception, have been used to demonstrate on-line access to the recently developed Committee on Scientific and Technical Information (COSATI) inventory of government sponsored work now in progress in the area of information sciences and technology. The report was prepared to assist an ad hoc subgroup of Panel 2 of COSATI to determine the state of the art and availability of systems that could provide on-line access to the COSATI inventory. The systems, which are described in terms of acceptability, effectiveness, performance, and availability are: (1) Data Corporation's Data Central, (2) Computer Corporation of America's 103, (3) Lockheed Research Corporation's DIALOG, and (4) System Development Corporation's Language for Utility Checkout and Instrumentation Development (LUCID) and Time-Shared Data Management System (TDMS).
