The Fair Use Doctrine is probably the most important exemption to copyright protections for educational settings, allowing many uses of copyrighted works for the purposes of teaching and research. However, not all use is fair use, simply because it occurs in an academic setting.
Tools to help you determine Fair Use
Fair Use Analysis Tool: guides users through the process of determining if a use is fair. This was developed by The University of Minnesota Libraries.
Factors for Fair Use: Another look at the analyzing the factors for Fair Use from Purdue University.
What is Fair Use?
The four factors to be considered in determining whether or not a particular use is fair:
The purpose and character of the use, including whether such use is of commercial nature or is for nonprofit educational purposes
The nature of the copyrighted work
The amount and substantiality of the portion used in relation to the copyrighted work as a whole
The effect of the use upon the potential market for, or value of, the copyrighted work
The distinction between fair use and infringement may be unclear and not easily defined. There is no specific number of words, lines, or notes that may safely be taken without permission. Acknowledging the source of the copyrighted material does not substitute for obtaining permission.
The safest course is always to get permission from the copyright owner before using copyrighted material. The Copyright Office cannot give this permission.
When it is impracticable to obtain permission, use of copyrighted material should be avoided unless the doctrine of fair use would clearly apply to the situation.
