Recently revised to coincide with the opening of the Manuscripts reading room in the new British Library building, this is essential reading for anyone beginning research in the Department of Manuscripts. Its main purpose is to list the many catalogues and other aids to the Department's collections, both those which have been published and those which are unpublished and only available in situ. In addition, useful information is provided for those whose work involves consulting charters and rolls, seals, papyri, and ostraca.
