What is Fair Use?
"Fair Use" is a provision of copyright law that allows us, under some circumstances, to use copyrighted material without first obtaining the author’s permission. Fair Use is intended to balance the rights of copyright holders with the interests of the general public.
Four factors are used to determine fair use of a work:
Before using a work or portion of a work without obtaining permission, it is important to make a "good-faith" analysis of how these four factors apply to your situation. Failure to show good-faith may weigh against a claim of fair use in a court of law. All four factors must be considered and weighed, but there is no clear-cut formula for applying them. The table below describes more specifically what kinds of uses favor a claim of fair use, and those that do not. Even if one factor seems to weigh in favor of fair use, there may be other factors that weigh against your use without the author's permission. For example, you may be using the material for educational purposes, but on the other hand this use may inhibit sales of the work. In such a case, it would be wise to obtain the author's permission.

If Fair Use Does Not Cover My Use, How Do I Get Permission from the Author?
If you are not confident that your use would favor a claim of fair use, then it is necessary to get permission from the author (or author’s agent) before you use the material. Some authors may freely grant permission to use the material as described. Others may offer permission but charge a royalty fee. Royalty fees can vary widely depending on the material and the intended use. Some authors may deny permission.
