To determine whether a use is fair requires four factors:  1. The first factor is the purpose of the copying, and copying to support an educational use.  2. The nature of the copyright work.  Is the copyright published or unpublished. 3.  How much has been copied in relationship to the copyright as a whole?  Is the amount of the original work used reasonable?  4.  The effect of the use upon the potential market for or value of the copyrighted work. Does the new work appeal to the same audience as the origianl work?
