In the past seventy years the activities of Plaid Cymru have become an increasingly important feature of the British political scene. Its complete archives are therefore of considerable interest as a body of source material for research. The archives consist of the following: pamphlets, leaflets etc. published since 1926; complete runs of both party newspapers – Ddraid Goch and Weish Nation; books published by, and on behalf of, Plaid Cymru; programmes and minutes of the Party Conference; minutes of the meetings of the National Council of Plaid Cymru: and the internal memoranda and publications of the Plaid Cymru Research Group.
