Census maps from 1871 now online (UK)

"Digital versions of the original Registration District maps from the 1871 census (Catalogue reference RG 18/1-110) are now available to browse and download at cassinimaps.co.uk. The maps are based on the Ordnance Survey 'Old Series' but were hand annotated to show the Registration Districts of England and Wales as they existed then. This additional hand-drawn information makes the maps a vital resource to family and local historians, as well as offering a fascinating geo-political snapshot of how England and Wales were administered at the time of the 1871 census. Cassini used scanned images of the originals that were then digitally stitched together to create a seamless mosaic of mapping. The maps are free to view online and you can search by postcode, place name, parish and district name. There is a charge to download the maps"
