Library Journal : by James K. Deane, Library Assistant at Emporia Public Library, Kansas This self-teaching guide covers electricity and electronics theory in enough detail (the introductory chapters on basic electricity and magnetism are excellent) to be useful to both beginning hobbyists and more advanced students. Readers can test their mastery of the material with the chapter quizzes and a final exam; the answers are in the appendix. A terrific resource for all libraries..
