The Open Content License is a share-alike public copyright license which can be applied to a work to make it open content. This license is not compatible with any other license in that it requires derivative works to be licensed under the Open Content License. With the exception of media and handling costs, it forbids charging for copies of a licensed work, but does not otherwise forbid commercial use.
The Open Content License, dated July 14, 1998, predates the GNU Free Documentation License (GFDL) and other non-software public licenses, though discussions were held between David A. Wiley, creator of the Open Content License, and Richard Stallman, leader of the Free Software Foundation, who created the GNU General Public License for software and would create the GFDL. The license text is titled "OpenContent License (OPL)" and the license is published at http://opencontent.org/opl.shtml. "OPL" stood for OpenContent Principles and License. Another license released a year later, also by the Open Content Project is called the Open Publication License.

“I was not content to believe in a personal devil and serve him, in the ordinary sense of the word. I wanted to get hold of him personally and become his chief of staff.”
—Aleister Crowley (1875–1947)
“Surely the fates are forever kind, though Nature’s laws are more immutable than any despot’s, yet to man’s daily life they rarely seem rigid, but permit him to relax with license in summer weather. He is not harshly reminded of the things he may not do.”
—Henry David Thoreau (1817–1862)
