There are four factors that will help determine whether the use made of work is fair use. The purpose and character of the use, including whether such use is of a commercial nature or is for non-profit education purposes;

- The nature of the copyrighted work;
- The amount and substantiality of the portion used in relation to the copyrighted work as a whole; and
- The effect of the use upon the potential market for or value of the copyrighted work.
So it would seem that it’s “fair use” if…
- The copying is for educational use;
- The original material is mainly facts and is published;
- You use portions to make your point, not whole sections; and
- You’re not taking potential sales away from the original o You’re not providing copies just so your students don’t have to pay for the books (or original source materials).
