Cambridgeshire's Register Offices are wholly separate from the Archives Service.

The Register Offices can supply copy birth, marriage and death certificates for their area from 1837 to the present day, but they do not have any other records of genealogical or local historical value. 

Note that a microfiche set of the General Register Office index is held at Cambridgeshire Archives, covering the years 1837 - 1999.
