I found the articles on Copyright Issues quite informative!  I especially liked the Teachers" Guide that indicates specific "Dos" and "Don'ts" for using copyrighted materials.  It was great to learn more about teachers' rights to use works of others for their classes; however, I was unaware of some of the specific rules about the number of copies and the number of times that you can use copyrighted works within a certain time period.  It is helpful to know this information.

I have always emphasize to my students the importance of citing their sources when they use the Internet for research, and I strictly forbid their use of "copy and paste" for projects.
