Typically, the CD version of a printed book does not contain animation.

It is basically a pdf type of file that would contain all of the pages/images that would be in the actual book. The price is cheaper because the cost of materials & labor to produce the CD is lower.

On the plus side, you could print out specific pages and take them to your bench while tying. The down side is that you would obviously need to be at your PC to browse thru the CD version.
