Public Domain

What is Public Domain?

The Public Domain encompasses:

  • Works published in the U.S. prior to 1923;
  • Works whose copyright has expired or were not renewed;
  • Works for which the copyright owner has intentionally and explicitly "dedicated" it to the public domain;
  • Works created by U.S. Government employees during the course of their employment;
  • Works which do not qualify for copyright protections (such as ideas, common knowledge, data points etc.).

Public domain is different than "publicly accessible" or "free online." Read more about the Public Domain here.

Government Publications

Everything published by the US Federal Government is free of any copyright restrictions. The research, reports and websites can be useful resources for your courses.

 

  • A great place to start a search is USA.gov
  • Try to search a specific agency's website.  A-Z List of Federal Agencies. Many times these materials are not retrieved with simple Google searches.  

Here are some examples of US Federal Databases:

  • The Homeland Security Digital Library is a collection of documents related to homeland security policy, strategy, and organizational management. Topics include maritime, unmanned aerial systems, terrorism, epidemics and many more. 

 

  • SciTech Connect is a collection of science, technology, and engineering research information from the U.S. Department of Energy.
