What is Fair Use?

Fair Use is a set of limitations to the complete and exclusive rights that a copyright owner holds for any creative work.  Where Creative Commons licensing is selected by the creator to allow specific uses of a work, the doctrine of Fair Use apples to any copyrighted work, and does not require any permissions from the creator, but the use must comply with the four factors listed below.  Fair Use does not necessarily allow for remixing, reuse, and/or revision as creative commons licenses do.  

Because Fair Use allows the use of creative content without permission of the creator, there are set restrictions on when Fair Use can be cited to use a work.  

From the U.S. Copyright website: 

Section 107 (of U.S.Copyright law) contains a list of the various purposes for which the reproduction of a particular work may be considered fair, such as criticism, comment, news reporting, teaching, scholarship, and research. Section 107 also sets out four factors to be considered in determining whether or not a particular use is fair.

  1. The purpose and character of the use, including whether such use is of 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
  4. The effect of the use upon the potential market for, or value of, the copyrighted work

The distinction between what is fair use and what is infringement in a particular case will not always be clear or easily defined. There is no specific number of words, lines, or notes that may safely be taken without permission. Acknowledging the source of the copyrighted material does not substitute for obtaining permission.

The 1961 Report of the Register of Copyrights on the General Revision of the U.S. Copyright Law cites examples of activities that courts have regarded as fair use: “quotation of excerpts in a review or criticism for purposes of illustration or comment; quotation of short passages in a scholarly or technical work, for illustration or clarification of the author’s observations; use in a parody of some of the content of the work parodied; summary of an address or article, with brief quotations, in a news report; reproduction by a library of a portion of a work to replace part of a damaged copy; reproduction by a teacher or student of a small part of a work to illustrate a lesson; reproduction of a work in legislative or judicial proceedings or reports; incidental and fortuitous reproduction, in a newsreel or broadcast, of a work located in the scene of an event being reported.”

Copyright protects the particular way authors have expressed themselves. It does not extend to any ideas, systems, or factual information conveyed in a work.

The safest course is to get permission from the copyright owner before using copyrighted material. The Copyright Office cannot give this permission.

When it is impracticable to obtain permission, you should consider avoiding the use of copyrighted material unless you are confident that the doctrine of fair use would apply to the situation. The Copyright Office can neither determine whether a particular use may be considered fair nor advise on possible copyright violations. If there is any doubt, it is advisable to consult an attorney.

Because we are working in an educational institution, we often use other's creative works in the classroom through the doctrine of Fair Use.  The advantage of Creative Commons licenses is that this use is granted by the creator up front, there is no question about whether the use meets the Fair Use doctrine.  As faculty publish educational materials on the web, and share content outside the bounds of a classroom, CC licensed materials guarantee that this use does not violate the copyright of the creator.  With Fair Use, there is never a clear answer to whether content can be used, especially in a public form like the Internet, each case is decided individually based upon the four factors.

Expired Copyright - Public Domain

In the U.S. there are multiple ways for a copyrighted work to enter the Public Domain, that is, to no longer be covered by Copyright law.  

  • Works that have no copyright claims by the creator (see CC0 licensing)
  • works where the copyright has expired
    • this includes any work created before January 1st, 1923
    • for any work published after 1977, the copyright is retained by the creator/s until 70 years after the death of the creator/s.
  • works where the copyright owner failed to follow copyright renewal rules
    • some works published after 1923 and before 1964
      • works made during this time can still be under copyright protection if the creator properly renewed the copyright.  For these works, you should check with the U.S. copyright office to confirm either renewal or that the work is in the public domain. 

It is important to note that in some countries the limitation on copyright is only 50 years after the death of the creator/s.  So when finding content on the Web, you may come across content on foreign websites (look for Australia in particular) that have content available that is in the public domain in that country, but not in the U.S.  You should not use these materials as public domain materials since the copyright has not expired in the U.S.
