I happen to love The Guitar Grimoire for the way he charted everything, although some of it is very redundant and the way he explains theory can be completely overhauled. lol
Shawn Lane, Sid Wolf, Buckethead, and myself all love Thesaurus of Scales and Melodic Patterns by Nicolas Slonimsky
Also Sid turned me on to a very very complete book called the Complete Thesaurus of Musical Scales by Masaya Yamaguchi
