Book publishing with Drupal

Cool ... for anyone interested in online book publishing, Drupal offers a "book" content type that does a lot of the "magic" of page linking for you, creating links like next, previous, and up. If you're collaborating on a book, it also offers access control and permission features, which is also very cool.

As of Drupal version 6.x, I find the Drupal navigation system to be a little cumbersome, so if you're looking to get started with it, I recommend this Drupal help page on Book publishing. Also, if you're not familiar with it, the admin_menu module helps to simplify Drupal's administration menu system quite a bit.
