The scope of the Museum, strictly, is the history of these subjects in Wales in the post-medieval period, but they cannot be interpreted properly without considering the British, European, and up to a point, world-wide contexts, and this is reflected in the Library's collection. It contains approximately 40,000 volumes, 200 maps, and 260 current periodical titles.
