This book may appear somewhat dated, since with its early 90's publication it was written before personal computers had made quite the inroads into taking the pain and frustration out (a lot of it at least) of learning Morse code. It is a solid survey of the code, its origin, history, uses, and how to learn it. Cupled with a shareware CW trainer (such as Morse Academy, SuperMorse, NuMorse, for PC, or MorseTrainer for Mac) it is all you really need to get conversant in code. A good starting point, and a bargain at the price.
