Still The Beast Is Feeding: 40 Years of Rocky Horror by Rob Bagnall and Phil Barden is an amazing new UK book from Telos Publishing (available on amazon.com) about the entire 40-year history of Rocky Horror! I bought a copy recently, and want to recommend it to all devoted Rocky fans. The book is 416 pages with eight pages of rare color photos, and took the authors four years to compile. It covers every aspect of the play's creation, original productions and long touring history, the film, Rocky's influence on pop culture, and much more. Eighteen new interviews and a wide variety of sources give the fans a guided tour through our favorite obsession. This is the big Rocky Horror event of 2013: pick up a copy!

Yep, best Rocky book out there. I can't think of anything important they didn't cover. (...except that Charles in Charge episode maybe.)
