Learn About Copyright: Using Copyrighted Works

How to Use Copyrighted Works

There are several ways for people to appropriately use works they don't own. Here are some examples:

  1. Obtain permission from the copyright owner.
  2. Buy, license, or use an existing license for the work. MC Library has licenses to a large number of e-books, databases, streaming films, and more, that MC-affiliated users can use for educational and non-commercial purposes.
  3. Use an item in the public domain. Learn more about public domain below.
  4. Use a copyrighted work under the fair use doctrine. Learn more about fair use below.

Remember, citations are always required for works that you did not create. Not citing your sources is considered plagiarism and is a violation of Montgomery College's Student Code of Conduct. Appropriately using a work does not mean you don't have to cite it!

Public Domain

Public domain refers to works that are not protected by copyright or any other intellectual property protection. Works in the public domain are owned by the general public, so the work can be used by anyone.

Works can become part of the public domain in different ways. Click on the other tabs in this box to learn more about how a work can enter the public domain.

Copyright protection does not last forever. The duration of copyright varies depending on when the work was created. Once copyright protection of a work expires, the work enters the public domain and anyone can use the work.

  • Works created on or after January 1, 1978 are protected by copyright for the life of the author + 70 years.
  • If the work was created by an employee for an employer, or if the work was created anonymously or under a pseudonym, copyright protection lasts for 95 years from publication, or 120 years from creation, whichever is shorter.
  • Works created before 1978 have different copyright duration rules. For full details, see the Duration of Copyright link in the box on the right.

CC0 and public domain license symbols.Copyright owners can chose to place their works in the public domain.

You can tell if a work has been placed in the public domain by the owner if it contains various marks or statements. For example, you may see a "CC0" mark (Creative Commons 0), a "no rights reserved" statement, or a statement that "this work is dedicated to the public domain."

An item may be ineligible for copyright if it doesn't meet various elements of the legal definition of copyright. For more details and examples, visit the Copyright page of this guide. Remember that just because an item isn't eligible for copyright protection doesn't mean it isn't eligible for other types of intellectual property protections, such as patents or trademarks.

Fair Use

"Fair use is a legal doctrine that promotes freedom of expression by permitting the unlicensed use of copyright-protected works in certain circumstances." 

Section 107 of the Copyright Act covers fair use. It provides four factors to consider when determining if the use of a copyrighted work constitutes fair use. Click on the other tabs in this box to learn about these factors.

In addition to the factors provided in the Copyright Act, using an unlicensed copyrighted work for criticism, comment, news reporting, teaching, scholarship, or research is more likely to be considered fair use.

Copyright users must decide for themselves if their use constitutes a fair use. But consider carefully, because copyright owners can sue for copyright infringement! If the court finds that your use of the work does not qualify as a fair use, the copyright owner may win monetary damages.

Purpose and character of the use: noncommercial uses (such as for nonprofit or educational use) are more likely to be considered fair use.

Nature of the copyrighted work: using factual works (like news stories or technical articles) are more likely to be considered fair use than creative works (like novels or music).

Amount of the work used: using a small portion of the copyrighted work is more likely to be considered fair use than using a large portion of the work. In addition, using an important part of the work may make the use less likely to be fair.

Effect of use on value of the work: if the unlicensed use of a copyrighted work has a negative affect on the market value of the work, it is less likely to be considered fair use.
