The original books of enumerators’ returns for the censuses of 1841, 1851, 1861, 1871, 1881, and 1891 for England, Wales, the Channel Islands, and the Isle of Man are at the Public Record Office in Kew. Those for Scotland are in the General Register Office of Scotland, in Edinburgh. Microfilm copies of selected portions of these six censuses are in libraries and record offices throughout Britain. This guide shows what microfilm is available and where, and it provides–county by county, library by library–a breakdown of local holdings and the registration districts that are covered.
