What is copyright?

 "Only one thing is impossible for God: To find any sense in any copyright law on the planet." - Mark Twain

Copyright = the right by creators to control their original works fixed in a tangible form. These could be print or electronic, creative or scholarly, articles or images. Copyright is automatic, so works do not need to be published or formally registered to belong to the creator. For a specific length of time, creators and designees possess the exclusive right to reproduce the work, make derivative works, distribute copies, and perform or display the work publicly. Significant exceptions apply. This guide explains.

What is Fair Use?

Fair use = copyrighted material copied for a limited, "transformative" purpose: comment, criticism, parody, new interpretation, etc. Fair use does NOT require you to pay a fee or get permission from the rights holder. 

The American Library Association's handy Fair Use Evaluator tool will help you decide when use is fair.

Still have unanswered questions? Try using Columbia University's Fair Use Checklist (PDF).

Public Domain

The public domain contains creative works that are not protected under Public DomainU.S. copyright law and free for anyone to use. Works usually enter the public domain because the copyright has expired or the rights holder didn't renew the copyright.  Stanford University offers more information.

How do I know if a work is in the public domain?

Consult Peter Hirtle's useful chart illustrating Copyright and the Public Domain in the United States (2014).
