Several months ago, author Rogers Cadenhead released the first book detailing MT3 - the Movable Type 3.0 Bible Desktop Edition. Since Anil mentioned the book in a MT news post on MT books, I thought I would put my 2 cents in about this book.
The first thing you should know is that the MT3 Bible is not a book for non-technically-oriented beginners. The book is filled with great information, but if you are looking for the simplified introduction to Movable Type, this isn't it. Many of Roger's instructions are in the form of Unix shell commands that you would use to manage files on a web server. In fact, the book's second chapter is on how to prepare your web server for Movable Type. If you're like me, someone who doesn't speak Unix, and would rather eat only lima beans for 3 days straight than to try to install MySQL or missing Perl modules on a Unix server, many of the instructions will not be helpful.
That said, the book is a step up in comprehensibility from the MT manual. If you've been struggling through the manual, the MT3 Bible may help provide clarity on various topics. In addition to preparing a web server, the MT3 Bible offers chapters on installing MT, configuring a weblog, writing a weblog entry, organizing a weblog, publishing photos, template tags, designing a weblog using templates, comments, trackbacks, backing up a blog using the export feature, adding search capabilities, importing entries from other weblogs, connecting to MT with XML-RPC, using plugins, publishing RSS files, the Atom syndication format, and how to design a plugin. Even if you've read all the tutorials in LMT, you may still find much of this book helpful. In particular I like the section that goes into detail on how to make use of various plugins that are available for MT. I also like the section that explains the templates in detail. The book is filled with useful tables of code that might be helpful if you do any customizations to your MT blog.
