Public Domain
A public domain work is a creative work that is not protected by copyright and which may be freely used by everyone.
The reasons that public domain works are not protected include:
- The work does not meet the requirements for copyright.
- The copyright for the work has expired.
- The author/creator failed to satisfy statutory formality to perfect the copyright.
- The work was created by the U.S. Government. (see note)
Once a work enters the public domain, it cannot be reclaimed by the original copyright owner.

These may be photocopied without restrictions. However, there is a small number of U.S. government publications which have been copyrighted, and a notice will appear in them. These publications are subject to the college's general copyright policy. Examples of restricted government documents include classified information and trademarks (ex. Smokey the Bear).
