Northampton Archaeological Society was formed in 1974.  Thirty years later NAS was still going strong and it was decided that an overview of the county's archaeological record should be published.  The book, The Archaeology of Northamptonshire, was published in 2004, with 200 pages and 125 illustrations (black and white and colour).  It was edited by Martin Tingle with the period chapters written by a variety of authors.
