A couple of books I'm looking forward to:

Willy Martello & the El Rey Club (Searchlight) -- Andy Martello is self-publishing a book on this subject later this summer.
A labor of love. He's fundraising for the book -- see prior posts on the subject. Book & photos should be interesting.

Jay Sarno -- As announced at his educational seminar at the club convention, David Schwarz of UNLV Gaming Library fame, announced that he's publishing a book on Sarno later this year. His other books have been interesting reads, and this one should enlighten us on the "father" of Caesars Palace and Circus Circus.
