The Copyright Act of 1976 grants a number of exclusive rights to copyright holders, including:
Even so, there are legal exceptions to these rights, within limitations, that allow for the use of copyrighted work without prior permission of the copyright holder.
Here are three options for the lawful use of copyrighted works without prior permission from the copyright holder. These exceptions to the exclusive rights of copyright holders are written into the Copyright Act of 1976.
1) "Fair Use" as outlined in section 107. The Fair Use exemption can apply in a variety of situations, including some which are non-educational.
2) "Face-to-Face Teaching" as outlined in section 110(1).
3) "The TEACH Act" as outlined in sections sections 110(2) and 112(f). It is different from "Face to Face Teaching" and covers situations that may occur in the digital environment.
"Public Domain" defines works that are not covered by copyright, trademark, or patent laws for a variety of reasons as outlined in sections 301-305 of the Copyright Act.
There are four common ways that works wind up in the public domain:
In the United States, all works published prior to 1923 are automatically in the public domain because the copyright has expired. Works published after this date may or may not be in the public domain depending on whether the copyright was renewed.
