I've been told by students in my classes that they have used this feature to read about and solve a design problem, before they even purchased the book!Give it a try. Plug in a design topic and see what comes up. Page around, and you will also see some of the detailed illustrations.
If you like to look at a book before you buy it, this feature is great.
