There are three major exceptions to the copyright law that are commonly used by educators: fair use, face-to-face instruction, and virtual instruction. Exceptions allow for the use of a work without requesting permission from the copyright holder and potentially paying fees.
If the use does not qualify under face-to-face instruction or virtual instruction, then fair use is generally utilized because it is much broader and more flexible.
It is the decision of the individual who is using the work as to which exception is applicable. It should be a conscious decision not a decision by default. It is the responsibility of all members of the Purdue University community to understand the exception and to make a good faith determination that their use of a copyright protected work is authorized under one of the exceptions. A good faith determination means that the individual must understand the exception they are selecting, be able to articulate it, and be able to reasonably apply it to their specific situation. If none of the exceptions are applicable, then permission should be requested for the use of the work.
