§ 107. Limitations on exclusive rights: Fair
use38
Notwithstanding the provisions of sections
106 and 106A, the fair use of a copyrighted work, including such use by
reproduction in copies or phonorecords or by any other means specified by that
section, for purposes such as criticism, comment, news reporting, teaching
(including multiple copies for classroom use), scholarship, or research, is
not an infringement of copyright. In determining whether the use made of a
work in any particular case is a fair use the factors to be considered shall
include-
(1) the purpose and character of the use,
including whether such use is of a commercial nature or is for nonprofit
educational purposes;
(2) the nature of the copyrighted
work;
(3) the amount and substantiality of the portion
used in relation to the copyrighted work as a whole; and
(4) the effect of the use upon the potential
market for or value of the copyrighted work.
The fact that a work is unpublished shall not
itself bar a finding of fair use if such finding is made upon consideration of
all the above factors.
