Philip K. Dick (Pocket Essential series)
"Pocket Essentials" is a dynamic new series of  books that are short, snappy, and easy to read. Packed with facts, as well as opinions, each book has all the key information you need to know about such popular topics as film, television, cult fiction, "parapolitics," and more. In addition to an introduction to the subject, each topic is individually analyzed and reviewed, examining its impact on popular culture. There's also a handy reference section that lists related web sites and all the weightier (and more expensive) books on the subject. For media buffs and students, these are great little entry-level books that build into an essential library.
