Welcome! And thanks to OKF for setting us up with a forum here.
The Free & Open Works! wiki is a database of thousands of free and open works (as well as select other works under more limited NonCommercial or NoDerivatives licences).

Unfortunately it’s running slowly at the moment because it gets free hosting. It’s a Semantic MediaWiki site, which makes finding it a new home a bit difficult.
