WHEN the “Hatfield and its people” series of booklets was first published some 60 years ago, it was rightly regarded as an exceptionally authoritative and informative work. It has since remained unchallenged as the prime source of reference for anyone interested in the history of Hatfield, Hertfordshire, England. Recognising its enduring value, and with the original booklets long out of print, Hatfield Local History Society in 2014 issued a facsimile edition of the original booklets, each with its own ISBN and index. A Cumulative index to the series was added in 2015. This Compendium concatenates the twelve parts into a single volume, with a cumulative index at the end. The reader is directed to the forewords and introductions to the individual parts for information about the background and subject matter.
