The British Library's collections in the field of Slavonic, East European and Soviet Studies are the largest in the UK, and probably in Western Europe.
The policy of the East European Section is to acquire, as widely as possible, material of research value published in all Slavonic and East European languages covering subjects in the humanities and social sciences. You can find a comprehensive introduction by country on the British Library website.
The British Library Sound Archive holds extensive published and unpublished material from across Eastern Europe including wax cylinder recordings from Bosnia and Albania. You can see a longer essay on what they have, and search the catalogues by following the link below.
