I saw jump blues and swing master Junior Watson at a bar up in Minn once. We were smoking cigars during the break and I asked him where he learned all the cool chords he uses, and he said "get the Mickey Baker books". At the time I was guitarist in an Atlanta bar blues/swing band and tried, but those books are tough.

I like the classic "Chord Chemistry" book. It has all of "Guitar George's" chords, and a really good appendix on theory that helped me immensely. ETA: by Ted Greene.
