National Library of Wales

The National Library of Wales, in Aberystwyth, is the national legal deposit library of Wales and is one of the Welsh Government sponsored bodies. It is the biggest library in Wales, holding over 6.5 million books and periodicals, and the largest collections of archives, portraits, maps, and photographic images in Wales. The Library is also home to the national collection of Welsh manuscripts, the National Screen and Sound Archive of Wales, and the most comprehensive collection of paintings and topographical prints in Wales. As the primary research library and archive in Wales and one of the largest research libraries in the United Kingdom, the National Library is a member of Research Libraries UK and the Consortium of European Research Libraries.

At the very core of the National Library of Wales is the mission to collect and preserve materials related to Wales and Welsh life and those which can be utilised by the people of Wales for study and research.
