Reddit reviews Joshua Tree Rock Climbs

Miramontes is great. http://www.amazon.com/Joshua-Tree-Climbs-Robert-Miramontes/dp/0982615442 It's pretty comprehensive. Nice color pictures. A good amount of "fluff/culture/history" to keep you busy on the car ride as well.

not much sport. i like the mostly comprehensive book from wolverine publishing.

There is one from vogel that has a lot of the history and interesting stories but it's a little bit more limited in routes(though still pretty comprehensive). it has a green cover and is called classic joshua tree routes & bouldering.(though that might just be the first edition of it)
