Copyright does not prohibit all copying or replication. In the United States, the fair use doctrine, codified by the Copyright Act of 1976 as 17 U.S.C. Section 107, permits some copying and distribution without permission of the copyright holder or payment to same. The statute does not clearly define fair use, but instead gives four non-exclusive factors to consider in a fair use analysis. Those factors are: the purpose and character of your use the nature of the copyrighted work what amount and proportion of the whole work was taken, and the effect of the use upon the potential market for or value of the copyrighted work. http://en.wikipedia.org/wiki/Copyright#Limits_and_exceptions_to_copyright Mar 15 08, 2:20 AM
