The Instructional Use of Learning Objects

I'm still purusing resourses on learning objects and found this very informative online book, "The Instructional Use of Learning Objects." You can read the full text of the book here for free. In addition, you can participate in discussions of book chapters with the authors and other readers, submit corrections, and discuss other issues related to learning objects, instruction, and learning. http://www.reusability.org/read/
