Found this referance table in library.
From: The Art of Knotting and Splicing

Pub. by Naval Institute Press
A great old standard of general knotting. ABOK still the referance champ. But,the new "Ultimate Encyclopedia of Knots and RopeWork" by Geoffery Budworth is great modern guide with over 1000 glossy pix that about bring it up to a coffee table, conversation piece grade. Mr. Budworth also did editing on latest versions of ABOK as well as instrumental in starting The Intnl. Knot Tyers Guild in England i beleive.
