Some of these books are informative, others are entertaining, and all of them will increase your understanding of both Puerto Vallarta and Mexico. Virtually all of these will be easier to find at home than in Puerto Vallarta. Although many of them are classics and out of print, www.amazon.com [1], www.barnesandnoble.com [2], and libraries have used copies. Take some along on your trip. If you find others that are especially noteworthy, let us know. Happy reading.
