Gentlemen,
Barley has two books out. The first (2014) is the most informative, a pretty comprehensive botany of British saws. Of its' 731 pages the majority (pp. 103-670) is an annotated listing of British saw makers.
Pages 5-22 cover my area of interest, the making of saws, but without much useful detail.
The smaller volume (2016) is nice because it has color pictures. It presents a small amount of information that's not covered in the first book.
Both are extremely well written and edited, in sharp contrast to many woodworking texts.
