Joe Viola teaches at Berklee College of Music and came out with a few books.  I worked with volume II quite a bit.  At first I would just read through it to practice site reading since he covers all the chords and it starts becoming a beast when you have multiple double b’s or #’s.

The chord studies book works by going from major to dominant to minor to dminished all within one key.  So you can really work on one that you’re having trouble with.
