I agree "A New Guide To Rational Living" by Albert Ellis is one of the best books on Cognitive Therapy. It is rather intense, IMHO theoretical. An easier more hands-on but just as excellent is David Burns "Feeling Good". (David Burns worked closely with Albert Ellis during the writing of "New Guide To Ration. Liv.")"Feeling Good" is one of the Best books I have. Best of Cognitive Therapy but written on a more personal level, covers many areas of day to day living - it's great - A Real Winner!
