What is Copyright?

According to the Copyright Office, copyright is defined as a way to protect original and tangible works of authorship for both published and unpublished works. 

What does it protect?

Copyright can protect literary, dramatic, artistic, or musical works. 

What doesn't it protect?

It does not protect facts, ideas, systems, or methods of operation. 

What rights do authors have? 
  • Make and distribute copies 
  • Prepare derivatives based on the original work 
  • Perform the work publicly 
  • Display the work publicly

Fair Use

According to the U.S. Copyright Office, fair use is the unlicensed use of copyright-protected works in certain circumstances. 

The four factors of fair use are: 

  • Purpose and character of the use, including whether the use is of a commercial nature or is for nonprofit educational purposes
  • Nature of the copyrighted work
  • Amount and substantiality of the portion used in relation to the copyrighted work as a whole
  • Effect of the use upon the potential market for, or value of, the copyrighted work

Please see the U.S. Office of Copyright for More Information on Fair Use. 

Public Domain

Public domain works are free to use because they are no longer under copyright protection.

Generally, works published after January 1, 1978, are protected by copyright for the duration of the author's life plus 70 years. For works with anonymous authors, pseudonym authors, or works made for hire, the copyright term is 95 years from the year of its first publication or a term of 120 years from the year of its creation, whichever comes first.

Many public domain works are available through Hathi Trust, Google Books, and Internet Archive.


The TEACH Act (Technology, Education, and Copyright Harmonization Act) attempts to give distance instructors the same opportunities to show copyrighted works in their classroom as a face-to-face instructor would have. 
Requirements of the TEACH Act:

  • Accredited, non-profit educational institution 
  • Must be a part of the instructional lesson
  • Use must be limited to the number of students enrolled in the class
  • Must be behind technological safeguards, such as Blackboard.

Once a work is created and available, it's protected by copyright. Registering for copyright is voluntary, but according to the U.S. Copyright Office, it can be beneficial if the creator wishes to bring a lawsuit for infringement. 

Patent, Trademark, and Copyright

The difference between patents, trademarks, and copyrighted materials is that copyright protects literary, dramatic, or musical works or information. Patents protect inventions. Trademarks protect either a word, phrase, symbol, or design or any combination of those.
