Bookbindings in the British Library
The British Library contains a wide range of fine and historic bookbindings; however, books in the Library are organised primarily by subject rather than by binding so the Library has produced a guide to enable researchers to identity bindings of interest. The collection includes the oldest intact Western bookbinding, the leather binding of the 7th century St Cuthbert Gospel.
