1) "If you need to go up and down fixed ropes, this is the book you've been waiting for. On Rope is already being hailed as the bible of vertical or single rope techniques (SRT). Its 300 plus pages contain the most definitive text on rope techniques yet published, supported by over 425 detailed drawings, eight comprehensive comparison charts, three how-to workshops, and an extensive glossary....On Rope is sponsored by the Vertical Section of the National Speleological Society - the group whose members have pioneered the development of new rope techniques for nearly 30 years. It is the creation of two active members of the Vertical Section whose wide ranging experiences include vertical cave exploration and search and rescue on a national level. On Rope covers everything you need to know from ropes, knots, and harnesses, to ascending, descending, and belaying - plus a detailed program for training and practicing ropework."

Hervey Garrett Smith was the foremost marine illustrator of the 1950s and 1960s, and his wonderful drawings of traditional ropework quickly propelled The Marlinspike Sailor to cult classic status when it was published in 1956. With the addition of a section on modern, synthetic rope in the 1970s, its popularity has continued undiminished to this day. It teaches a few basic knots--the bowline, sheet bend, and rolling hitch, among others--and splices in three-strand and braided rope. But its real business is decorative rope and canvaswork--the traditional arts of the sailor--and here it has no equal. For a rope mat, a rope ladder, a sea chest, a ditty bag, a canvas bucket, a mast boot, and the best-looking rope fenders or heaving line in the marina, this is the book of choice."
3) "More than 75 knots and their uses. Hobbyists, decorators and tricksters will treasure this collection of useful, decorative and magic knots. From simple hitches to complex lariats, trick knots and rope tricks with step-by-step illustrations and instructions. Illustrations throughout."
4) "This handbook serves as a practical guide for all phases of knot techniques both practical and decorative in purpose. Much more than a reference work, the handbook leads the interested reader to the mastery of an artistic and absorbing hobby. Common types of work knots, such as hitches, sheepshanks, and bowlines are demonstrated along with a good explanation of blocks and tackle. There are sections on sennet braiding, ornamental designs, lashings, securing hawsers, boatswain s chair, hammock making, and various ties which provide an excellent foundation for understanding and executing general knot work and weaving. The detailed illustrations and clearly written text in this small book make knot tying easy for the beginner. More than 400 knots for all types of outdoor activities, crafts, trades, hobbies, and handicrafts are indexed by name and use, and illustrated"
