The company that publishes that book, Sequoia Publishing, also publishes a few more, very handy pocket sized books.
Probably the best is the "Pocket Ref".....this book has the most information in a small package that I have seen. Look it up, and you will be amazed.
They also have the "Pocket PC Ref", which tends to be a little dated, even though it is updated from time to time, technology stays pretty far ahead of it. BUT, if you are working with some older PC equipment, it could be helpful.
