For 20 years members of the Society have been transcribing and indexing the records of Cambridgeshire, including parish registers, the 19th century census returns, poll books, poor law papers and many miscellaneous sources. Copies of all the resultant transcripts are placed on open access at the County Record Office, Shire Hall, Cambridge and in the Library of the Society of Genealogists in London. Search services into many of the indexes are available at moderate cost.

It is current policy to publish all parish register transcripts and large indexes on microfiche, as projects are completed. Copies are for sale on the Society Bookstall.

Details of the holdings of CFHS project work at Cambridge Record Office are included in Genealogical Sources in Cambridgeshire, available from the Bookstall.
