Open Publication License
The Open Publication License replaced in 1999 the previous Open Content License from 1998. Both the two licenses differ substantially: The Open Publication License is not a share-alike license while the Open Content License is and the Open Publication License can optionally restrict the distribution of derivative works or to restrict the commercial distribution of paper copies of the work or derivatives of the work, whereas the Open Content License forbade copying for profit altogether.
According to the Free Software Foundation, the Open Publication License "can be used as a free documentation license" and is "a copyleft free documentation license provided the copyright holder does not exercise any of the 'LICENSE OPTIONS' listed in Section VI of the license." It is not, however, compatible with the GNU FDL.
Since May 2007 the Open Content Projects recommends instead using one of the Creative Commons licenses.
The Open Public License was analyzed in detail legal-wise by the author of Understanding Open Source and Free Software Licensing, Andrew M. St. Laurent, in 2004. The license was accepted as a free content license according to the Free Cultural Works definition.
A major work which used the Open Publication License was Eric S. Raymond's book The Cathedral and the Bazaar in 1999. Bruce Perens used the license for the Bruce Perens' Open Source Series of books. Also the Fedora project used the license for their documentation until around 2009/2010 when they switched to a CC-BY-SA license.
