Copyright and Fair Use

Copyright?
copyright is a form of protection provided by the government to the authors of "original works of authorship, including literary, dramatic, musical, artistic, and certain other intellectual works." This protection is available to both published and unpublished works, regardless of the nationality or domicile of the author. It is unlawful for anyone to violate any of the rights provided by copyright law to the owner of the copyright.

Fair Use?
Fair use is primarily designed to allow the use of the copyright protected work for commentary, parody, news reporting, research and education. However, fair use is not an exception to copyright compliance so much as it is a "legal defense." That is, if you use a copyright protected work and the copyright owner claims copyright infringement, you may be able to assert a defense of fair use, which you would then have to prove.
