Just got my copy of "Essential Articulate Studio 09". Even if you have been using Articulate forever (like me), you'll find lots of great tips and ideas to help with your learning projects. The book includes information on each Studio product along with tutorials and projects. The accompanying CD has trial versions of the software.
