The public domain includes works that are no longer in copyright or were never copyrightable. These works can be copied, distributed, or used for derivative works without restriction. But remember that if you use someone else's work, even if it is out of copyright, you must cite your source to avoid plagiarism.
Works published by the US federal government are all in the public domain and can make excellent course resources.
Works first published in the United States before 1923 are now all in the public domain, as are some works published later if the copyright was not renewed. The Digital Copyright Slider can help you determine if a work is now in the public domain.

An analysis of the four factors of fair use will not usually result in a clear yes or no answer to the question of can you use the material. Fair use is about finding a way to do what you need to do in a way that is most clearly legal and low risk.
