Not sure if you can still buy it but my all time favorite is "Fatal Calling". It teaches you a lot about how/when/why to call and the deers actions/reactions etc. If you plan to ever do some calling I would try to find a copy.

Anything from Roger Raglin is second best. Jeeeeemineey Chreeeeestmas. <img src=icon_smile_big.gif border=0 align=middle>
