Abstract
The development of computer software to assist the searcher when carrying out on-line information retrieval procedures using a microcomputer in place of a normal ter minal is described. Criteria for selection of a microcomputer for this purpose are given. A Cifer 2684 microcomputer ter minal which is Z-80 based with CP/M was chosen. The software allows the storage of user IDs, passwords and search data on floppy disc files which can then be sent to a host computer using simple commands. Data coming from the host can also be stored on disc. The system cuts down the time to enter a search, simplifies logging-on, and the accuracy of data can be checked before going on-line. Library staff have adapted easily to the terminal.
