Chesterfield
FC: The Official History 1867-2000, by Stuart Basson (2000)
THIS is a warts and all historical account of the club from its early days to the problematic Cox years.
The awful 1999-2000 season is also documented extensively in this book, which is of interest to Spireites fans and football historians alike.
