Many students will prefer to work from the CD. However, you can have a much more personalized book if you take pages from the CD and from the world wide web. Collect them so that you can alter them and customize them, for example on your hard drive or on a ZIP disk.

Transmission through the web is much too slow for students, and files get abandoned or lost. Why not capture pages as you find them?

The files MUST be in a local archive unless you are willing to wait when the internet is overloaded.

It is recommended and quite easy to integrate to link you lecture notes and the web pages. That can organize the material as it suits you best.
