This is the cumulative index to the "Hatfield and Its People" series of booklets about the history of Hatfield in Hertfordshire. When this series was published 50 years ago, it was rightly regarded as an exceptionally authoritative and informative work. It has since remained unchallenged as the primary source of reference for anyone interested in the history of Hatfield. Recognising its enduring value, members of Hatfield Local History Society have undertaken this reissue now including a comprehensive index for each title and this the cumulative index for the whole series. The complete list of 13 titles can be found in each of the booklets.
