Actually, most of the books are about Open E because they deal with electric guitars.

Checking through my piles of books: Acoustic Guitar "Slide Basics"; another Fred Sokolow book -- "Fretboard Roadmaps Slide Guitar" --; Brett Duncan's "Progressive Slide Guitar Licks"; Larry McCabe "101 Dynamite Slide Guitar Licks in Open E (Mel Bay); "Fast Forward Slide Guitar" (Wise); Mike Levine, "Slide Guitar Essential Skills" (Cherry Lane); Keith Wyatt, Acoustic Slide Guitar" (Warner Bros.); Wayne Riker, "Slide" (Alfred). I got something from all of them.

The one with the worst title -- 101 Dynamite Slide Licks, etc. -- is really one of the best, once you get the basic idea of open tuning down: it gives transcripts of some important blues songs, and then slows the licks parts down for you to work through in sequence. The other books usually just give you bits, or complete songs usually way too fast for the novice.

My experience with videos is that they are mostly a waste of money. They are either too simple or too complicated, and after one or two viewings you never look at them again. If anyone has experience with a good open tuning video, I too would like to hear it.
