              Fair use
  
        
Certain  acts normally restricted by copyright may, in circumstances specified in the law, be done without the authorization of the copyright owner. Fair use may therefore be described as the privilege to use copyrighted material in a reasonable manner without the owner's consent and allows the reproduction and use of a work for limited purposes such as criticism, comment, news reporting, teaching, and research. To determine whether a use is fair or not most copyright laws consider: 1) purpose and character of the use, 2) nature of the copyrighted work, 3) amount and substantiality of the portion used, and 4) effect of the use on the potential market. Examples of activities that may be excused as fair use include: providing a quotation in a book review; distributing copies of a section of an article in class for educational purposes; and imitating a work for the purpose of parody or social commentary.
