The Huntington Press is known for publishing books about Las Vegas. They have a very large number of books about gambling, but they also publish books by local authors about Las Vegas, its history, and its quirks.
The company is probably best known for it publication of the Las Vegas Advisor, a monthly publication--available in paper form or online version. A companion book that comes with the subscription is called the Pocket Book of Values, a book filled with coupons for deals in Las Vegas.
I get the POV each year, and while I don't use even 1/2 of the coupons, using only a couple more than pays for the book and gets you access to their online site. It's a good value.
