The Ashley Book of Knots - Clifford W. Ashley
The Ashley Book of Knots is an extensive encyclopedia and by far one of the most comprehensive works on practical knots.
An incredible resource with by far the clearest visual instructions on tying all kinds of practical knots. Much of the work presented is originally from The Ashley Book of Knots. For bondage, I recommend people learn the sheetbend and the midshipman's hitch.
A group of experienced riggers and skilled instructors that use videos to show a multitude of bondage ties. I recommend learning the burlington bowline if you need a new single column tie.
