Introduction
Educated people need textbooks:
A library is not always handy.
Books organize and present what
you have learned and more.
Class notes and handouts can be useful but:
Easily lost or misplaced.
Hand written materials difficult
to read.
Today we use many media: Video, sound tapes, printed
pages, internet.
Great convenience if all are put together on a Compact
Disk.
Easy to search.
Low cost.
Simple and cheap duplication.
Why use web pages?
