Query: This is an excellent reference

The first thing I loved about this book was the non-linear table of contents. The second thing was the topics themselves. So many eLearning books cover the basics and this moves beyond while remaining accessible and understandable to newbies. I've been designing eLearning courses for 10 years now but just bought this book as a reference for my office.
