jQuery Pocket Reference provides a very useful coverage of jQuery and the functionality it provides. It presents the key concepts and how to work with jQuery. This makes it sound like a book for beginners to jQuery (which to some extent it is), but it is also excellent for people with much more experience, who want to review what they know, and also have a good reference.
I’ve been using JQuery in one form or another for a number of years now. I can remember clearly the days in which jQuery was coming up and overtaking prototype.js as the premier browser DOM abstraction platform. This almost makes it seem like this book would be useless for me to read. Instead it makes it all the more worthwhile, helping plug in some gaps and giving some additional grounding to what I know.
I would definitely recommend reading this book to anyone who wants to use jQuery well. There is a wealth of knowledge captured in the book, and it is presented in a way that makes for both easy reading and a good reference. My electronic version has been well highlighted and marked up for future reference.
