I've seen tons of books on "How to Rock Climb" or "Rock Climbing for Dummies" or what have you. Wondering if there was any one that is particularly good. I've been indoor climbing for about a year now and have just started to take it outside. I've also seconded some trad climbs (fascinating). Anyway, don't worry, I'm not trying to learn how to rock climb from a book, but I'd like a good reference for different knots, trad placements, anchoring, etc. Any suggestions?
