I have been making them available at a local copy shop for students in my class. One problem I can imagine if I put them on the web is that students would be able to print them out from campus printers. This would be expensive for the university. Especially if putting books on the web became popular. Another problem is that someone else might take the notes and publish them in their name.
Students seem to appreciate it.
Photocopying 80 pages is much cheaper than buying any textbooks I know of. In part this is my answer to the rising costs of textbooks in an age when production costs must be going down. So I am looking for information and advice. Any pointers or stories of the experience others may have had with similar ventures would be appreciated. Please email me a copy of any thing you might post on this subject.
