Ah, the Public Domain: What does it mean? Why does it matter? How do I know?

Works in the PUBLIC DOMAIN are free from all copyright restrictions. It matters because you can do anything you want with PUBLIC DOMAIN works: republish, quote, write a screen play, choreograph, direct, sing, play, screen, post . . . . (Of course you must always CITE the work.)

ALL Works published before 1923 fall into the PUBLIC DOMAIN. . . . But wait! There are more!

All US Government Documents are in the PUBLIC DOMAIN. (NOT all state government docs, however -- you have to check.)

Published works between 1923 and 1978 without copyright notices are in the PUBLIC DOMAIN.

Published works between 1923 and 1963 with copyright notices, but the copyrights were not renewed are in the PUBLIC DOMAIN. Stanford University is working on a searchable database of the copyright renewal records received by the US Copyright Office. This project will save you a lot of research hours. Less than 10% of the copyrights in this period were in fact renewed. http://collections.stanford.edu/copyrightrenewals/bin/page?forward=home

Published works between 1978 and 1 March 1989 without copyright notices and without subsequent registration are in the PUBLIC DOMAIN.

In addition, an author may voluntarily place a work into the PUBLIC DOMAIN at any time.

See indiviual topics on this site for more information, for example Screen a Film.
