The need for subject access on OPACs has been widely recognised since their early development in the USA Markey, 1984 Matthews, 1985b. Many OPACs in UK academic libraries provide subject access to catalogue records, mostly through search strategics such as keyword access or subject headings searches. However, users do find subject searching more difficult than knownitem searching Markey, 1985 Bagnall and Jeffreys, 1986 so most OPAC systems provide help screens to assist users in their searches.
