This book has short write ups of an entire slew of OTR shows. Usually the staff and cast members are listed, and sometimes additional commentary. There are 301 pages of text, plus 32 pages of photos (usually with two to four images per page). It's a good resource for obscure information, but if you want to read something detailed about your favorite show, you probably won't find it here.
