The Royal Commission has been publishing the results of its research and material from its archive since 1911. The earliest publications were inventories of ancient and historical sites in each county, the last volume appearing in 2000. In 1975 the Commission published its first thematic book, Houses of the Welsh Countryside, and since then we have published over thirty titles covering all aspects of Welsh Heritage. Our entire catalogue is now available through our bookshop, with out of print titles now available as eBooks. The Commission also works collaboratively with other publishers on relevant works in line with our publication policy. Increasingly our work is available digitally in the form of detailed site reports, animations and web resources such as Coflein. We also publish newsletters, annual reports and the Heritage of Wales blog.
