Which Personality Type Books are The Best?


Hey, I'm not sure if I'm posting this in the right place, but I need some advice about which book to buy. I want to buy a book about cognitive functions, temperament and personality types. Which one would you recommend? I'm thinking about buying "Please Understand Me II" by David Keirsey. Would that be a good choice? I don't really know about any other similar books that might be better. I would really appreciate your input.
Neuroscience of Personality by Dario Nardi is a good one.

Gifts Differing: Understanding Personality Type by Isabel Briggs Myers if you want it from the source on MBTI.

Personality Type: An Owner's Manual, by Lenore Thomson.

Psychological Types by Carl Jung if you want it from the originator of the functions.

Well for a few reasons actually, I want to learn more about cognitive functions and such things and I think that a book will offer more in-depth descriptions. That's the conclusion I made by reading a few excerpts from books on the net. They seem a lot more informative, descriptive and organized than the information you can get on the internet. I can make notes in it and reference it, although you can do that on the internet too - it's also a personal preference I guess, I like reading from books.
In addition to what has already been said, you may find these resources - (1) (2) (3) - helpful for research. Respectively, they are 1) a wide compilation of Internet sources, 2) books, and 3) a conceptual sketch of the cognitive functions and their surrounding theory. (Thank you, any INTPs who may be lurking.) Best of luck =)
