Query: Great book. Useful and well-organized.

I found this book very useful. It's well laid out. It starts from the basics (so it may not be for everyone), but even though I don't consider myself a beginner, a tip for listservs saves me time every day. Especially useful is the appendix which includes up to date tools, forums, conferences, training organizations, etc. I plan to recommend the book to other faculty where I work who are implementing web-courses.
