There are some very good books out there for CBT. Make sure you shop for one with worksheets. Better yet, try to find one with daily exercises, worksheets, and prompts. There is a great deal of daily work required for CBT and it isn't going to work if you don't do it.

My favourite book was "CBT Journal for Dummies". I bought it for $17 (Cdn). It is an 84 day program.
