In the mid-1960s Dennis Jackson became one of the few full-time field archaeologists attempting to keep pace with the increasing rate of destruction caused by all aspects of modern development, particularly stone quarrying around Corby and gravel quarrying along the Nene valley. Much of value would have been lost without record if he had not been there to see it before it was machined away. His autobiography covers work on Neolithic and Bronze Age burials, numerous Iron Age and Roman settlements and an Anglo-Saxon cemetery. The book also includes reviews of pit alignments, Iron Age settlement studies and a proposed chronology for Iron Age pottery assemblages in Northamptonshire.
