There was a recent discussion on the JSMentors JavaScript mailing list about books to read to get you to the next level. There's been a lot of great feedback and suggestions thrown out and I wanted to offer up what I felt were good books/resources to carry you through the learning process. While I have list a number of books in the <a href="http://blog.reybango.com/the-big-list-of-javascript-css-and-html-development-tools-libraries-projects-and-books/#books-js">Big List page that I created</a>, narrowing it down into specific levels makes a lot of sense.

Note that some resources will overlap between levels. That should be expected as some books cover a wide breadth of language features. 

<h2>Introductory</h2>

These are books that will give you the fundamentals of the JavaScript language and get you started:

<h2>Intermediate</h2>

Once you've gotten an understanding of the basics, it's time to get a resource that will take you deeper and in many cases be your reference for years to come. These books fit that description.
