Copyfree Works

The license status of some works may be more complex than it at first appears here. In some cases, the license status listed for a given work is the "primary" license under which it is distributed. In several cases, parts of the work may be distributed under other licenses -- potentially even non-copyfree licenses.

Where present, descriptions are typically drawn from the claims of the projects themselves, and represent neither claims nor opinions of the Copyfree Initiative. Inclusion here (with or without description) does not constitute, and should not be inferred as, endorsement of any project.

Listings are presented for informational purposes only, and no representation is made as to the accuracy or utility of any information provided. Use at your own risk.

Filter Tags

To filter the list, click either the + or - link for a given tag.
