A few years ago I penned a series of free pdfs simply because I got tired of answering this classic question, "Where Does One Learn About Mentalism?"
Introduction to Mentalism is a resource book with an overview that can be found here -- http://s3.lybrary.com/free_ebooks/in..._mentalism.pdf (47 pages)
Learning to Cold Read is a similar resource and can be found here -- http://s3.lybrary.com/free_ebooks/le..._cold_read.pdf
I would point everyone to these two sources first in that they offer a list of the books and some videos you should avail yourself to along with a myriad of resources.
