Great for semi-experienced looking to build on knowledge.
Format: Paperback
Fantastic instructional manual if you already have some basic knowledge of anchors, ropework and climbing technique. It is written as an instructional manual for climbers looking to turn into guides so if you're brand new this probably isn't the best option for you.

Clear, straight forward, and authoritative
Format: Paperback
Excellent, straightforward information about how to stay safe at the crag. Every guy who's put his hand on a rock has an opinion about how to set anchors, belay, etc -- this book gives you the answers on how to do things the right way. Spend the 10 or 15 bucks and read the book. It might save your life.
