‘POLIS’ IN PARLIAMENT: COMPUTER‐BASED INFORMATION RETRIEVAL IN THE HOUSE OF COMMONS LIBRARY Available to Purchase

The Library provides information, documentation and research services to Members of the House of Commons. The organization of the Library and the history of POLIS (the Parliamentary On‐Line Information System) are described. The system became operational in 1980, and was set up by and is operated by Scicon Computer Services Ltd. Data entry is performed by the Library's Indexing Unit. Details of the telecommunications, software, hardware and database are given. UNIDAS retrieval software is used, and subject indexing is based on a thesaurus compiled by the Library. Most Library staff are being trained to use the retrieval facilities. Other offices of the House of Commons and of the House of Lords also have terminals linked to the system. Approved non‐Parliamentary users may also subscribe to POLIS via the public‐switched telephone network, Euronet or PSS. Other uses of computers by the Library are described.
