I bought this rule book to replace the one I lost in a house fire 15 years ago finally decided to get back into ASL. This was a great purchase the rule book came shrink wrapped and ready to be put into the binder.
This is the classic set of rules, with all the updates from 1985 to present (2009, in this 2nd ed, second printing).
A must have for the ASL system. Get this one.
