Fair use: certain uses of copyright-protected works do not require permission. (See Title 17, section 107)

The Four Factors

The following four factors are used to determine fair use:

1. The purpose/character of the use (eg. commercial vs. educational)*
2. The nature of the work
3. The amount of the material used (the greater the amount copied, the less likely it is fair use) or Substantiality (heart of the work)
4. The effect of use on the potential market (value of the work)

* Not all academic use is considered fair use!

* If you plan to copy or scan more than the fair share, DON'T, It's against the law!
