Open Publication License
This dates from 1999. Still operational? Probably overtaken by the Creative Commons licenses
"The Open Publication License, a license made primarily for printed materials like books, journals, and articles, operated within a framework of three requirements:
1. Attribution: when material from the open content is reused, the original author must be given credit.
2. Commercial uses: the licensor can choose whether or not to prohibit the for-profit sale of printed copies of the open content.
3. Derivative works: the licensor can choose whether or not to prohibit the revision or adaptation of the open content.
The Creative Commons licenses, currently the most popular open licenses for creative works, have adopted and adapted this same three-part framework. " (http://www.osbr.ca/ojs/index.php/osbr/article/view/797/768)
