The London 1871 Census, now also comes as individual Registration Districts, so why buy the full county set, if you don't need it. This set contains the Hampstead Registration District, and it contains images of the census books digitised from the microfilm.
The publishers are very proud of the superb quality of the scanned images. They've have worked from really excellent films copied from the first generation films at the PRO, and have then used the very best possible film scanner currently available to digitise the images at a high resolution.
Link to indexes to browse the areas and streets where your ancestors possibly lived, and it covers the whole of the Hampstead Registration District as it appears on the 1871 Census fiche.
Features of the CD set are: the ability to magnify an area to see further detail, print the current page, alphabetic street indexfor larger towns, and searchable area indexes. A full list of areas covered are in the PRO Class List.
