Copyright and Fair Use

This guide provides an introduction to the topics of copyright and fair use.

Copyright Law

Copyright Defined

Copyright law protects "original works of authorship fixed in a tangible medium of expression" for a limited period (17 U.S.C. §102). Copyrights are conveyed an individual(s) as soon as their work is fixed; formal registration is not required. U.S. copyright law (17 U.S.C.) applies to traditional media (books, records, etc.) and digital media (electronic journals, Web sites, etc.).

Copyright protects the following eight categories of works (17 U.S.C. §102):

  • Literary works
  • Musical works
  • Dramatic works
  • Pantomimes and choreographic works
  • Pictorial, graphic, and sculptural works
  • Motion pictures and other audiovisual works
  • Sound recordings
  • Architectural works

A copyright holder receives six exclusive rights (17 U.S.C. §106):

  • Reproduction
  • Distribution
  • Modification/derivative works
  • Public performance
  • Public display
  • Digital performance of sound recordings

 

Copyright: What Is Not Protected

Copyright does not protect:

  • Basic facts
  • Ideas, methods of operation, principles
  • Titles, names, short phrases, slogans (may be trademarked)
  • Generally, anything published in the US prior to 1929
  • Items already in the public domain 

Copyright Duration & Notification

Copyrights cannot be held in perpetuity. The United States Constitution (U.S. Const. Art. I, §8) states that "The Congress shall have Power ... to protect the progress of science and useful arts by securing for limited times to authors and inventors the exclusive right to their respective writings and discoveries." However, copyright protection does last a long time. See this table to understand more fully the complexities of copyright duration.

Keep in mind that, since 1989, a copyright notice has not been required to be displayed on an item; works that meet basic copyright requirements--an original work of authorship fixed in some form--are automatically protected by law. The copyright holder may add a copyright notice to their work to clarify to users who owns the content.

Copyright Exceptions

Fortunately, copyright law incorporates several exceptions that limit a copyright holder's six exclusive rights. For educational purposes, the most important exceptions are:

 

Fair Use

Fair Use

An important exception in the Copyright Act is the Fair Use Doctrine (17 U.S.C. §107). Fair use permits users, under certain circumstances, to copy, distribute, adapt, publicly perform, or publicly display portions or all of a copyrighted work without the copyright holder's permission. The following four factors must be addressed are weighed holistically to determine whether a given use qualities as fair use:

  1. The purpose and nature of the use
  2. The nature of the copyrighted work
  3. The amount and substantiality of the material used
  4. The effect of use on the potential market for or value of the work

Use the Fair Use Evaluator for step-by-step guidance in making a fair use decision, and/or contact library consultants for assistance. It's a good idea to print out a copy of your evaluation to keep as a record of your decision-making process. Remember, that ultimately only a court can determine whether your use is deemed a fair use.

Public Domain

Public Domain

A work falls into the public domain when its copyright term has expired or (for works governed by previous versions of US Copyright Law), a copyright owner failed to comply with necessary formalities. A copyright holder may also choose to place a work in the public domain, relinquishing their rights under the law. Materials produced by full time federal government employees in the course of their employment are usually in the public domain.
