Advanced Book Recommendations

[kyle]

I'm a fairly advanced WordPress developer. I just finished reading Professional WordPress Plugin Development by Williams, Richard, and Tadlock - which I thought was great - and I'm looking for suggestions as to what to read next. Anything else of this calibre that's worth recommending?

What exactly would you like to learn? If you want to learn more about Plugin Development, there is no other Book.
My Tips are:

• Read WP Development related Blogs: http://wpcandy.com/presents/every-wo...pcandy-follows
• Read the WP Codex
• Look how other Plugin Developers code their Plugins
• Read Books about PHP

Or:

• Just Code, Publish Plugins, Write Blog Posts

Although is more general overall, you may want to read Brad Williams own book, Professional WordPress or Aaron Brazells WordPress bible as both provide fairly in-depth material showcasing how the inner parts of WordPress function.

Thanks Jeffro. Professional WordPress might be worth taking a look at.

Soean, I was being intentionally vague. I essentially want books that are the quality of the Plugin book. I was thinking WordPress, but an advanced PHP book that's very good would probably be worth looking at.
