Ashley, Clifford W. The Ashley Book of Knots (057109659X)
First published in 1944, and reprinted many times since then, the latest reissue of this magnificent book contains, for the first time, fully illustrated details of all minor amendments and corrections that have come to light over the years. These have been collected and collated by Geoffrey Budworth with the help of other members of the International Guild of Knot Tyers.
