Searching the collection
All Welsh official publications since 1985 are listed in the OPAC. Publications before 1985 are listed on microfiche. Certain UK Parliament publications in the Welsh collection are treated as serials and are not searchable by title or ISBN. The TSO annual catalogues or online catalogue should be used to identify the number of individual papers. However, most publications in Welsh or of Welsh interest where additional copies have been purchased they are treated as monograph publications and are listed in the OPAC.
Documents laid before the Assembly are treated as monographs and catalogued individually in the OPAC.
The Welsh Government does not publish via TSO, and so its publications are not listed in TSO catalogues. Due to a centralised contract for legislation, Welsh Measures, Acts and Welsh Statutory instruments as well as UK Acts and Statutory Instruments are published by TSO, and included in their catalogue.
The National Assembly for Wales was established as a corporate body in 1999, but in 2007 the legislature and executive functions of the devolved government were formally separated, although a de-facto separation had been in operation for some time. Many publications initially published by the National Assembly for Wales, are now published by the Welsh Government (known as the Welsh Assembly Government until 2011).
