UPDATE: the farming and countryside index of the Welsh Agricultural College Available to Purchase

Update was started by the library staff of the Welsh Agricultural College (WAC) in 1974 to fill the gap in the information services provided as there was no comparable system to CAB for practical agricultural literature. It aims to provide a current awareness service, and also to create a database for the retrieval of information by specific subject headings. Unlike CAB it is not aimed at the scientific researcher, but at students coming to grips with the subject, often for the first time.
