New database on COPAC: The British Library Register of Preservation Surrogates - a national database with details of surrogate copies of printed books, journals etc. The copies have been made from originals held in a range of libraries and other institutions. At the moment the copies are normally in archival microform, but other formats may be available. The database is also the host for records of materials produced by the Chadwyck-Healey Nineteenth Century filming project
