==== Fair use ====
also known as "fair dealing", is the concept that unlicenced copyrighted work can be legally used without paying licencing fees or recieving permission of the copyright holder ( see [[w:Fair use| Wikipedia's article on fair use]]). Fair use is ''' explicitly prohibited on Wikisource.'''
As described by the [[w:Fair_use# Amount_and_substantiality| Amount and substantiality]] clause, reproducing whole works is not fair use. See the legal precedent set in ''Harper & Row v. Nation Enterprises'' (1985); as stated by [[w:Harper & Row v. Nation Enterprises|Wikipedia 's article on the subject]], the US Supreme Court "'' determined that fair use is not a defense to the appropriation of work by a famous political figure simply because of the public interest in learning of that political figure's account of an historic event.''" Further, "'' the use of less than 400 words from President Ford 's memoir by a political opinion magazine was interpreted as infringement because those few words represented "the heart of the book" and were, as such, substantial.''"
