 | Beginning June 15th, 2009, the Wikimedia Foundation began transitioning content on Wikipedia to be dual-licensed under both the GFDL and Creative Commons CC-BY-SA 3.0. As a result, this page may give inaccurate or outdated advice, and is in need of updating. |
A number of sites that mirror and fork Wikipedia may not be complying with all the terms of the GNU Free Documentation License (GFDL). This page should be used to track sites that use Wikipedia's GFDL text (but not CC-BY-SA). Wikipedia:CC-BY-SA Compliance should be used instead for newer mirrors (copied starting June 15th, 2009) that use Creative Commons Attribution Share-Alike (CC-BY-SA) text. Remember that the dual licence which applies to all new editor generated text since that date means that a site only has to comply with one of the licences. So check for compliance with either licence and make a note of which licence the site is most compliant with. The exception is text imported from external sources which may potentially be CC-BY-SA licensed only.
Please see Wikipedia:Mirrors and forks for instructions about adding new sites.
At the bottom of this page there is a section named "Former content users" that is used for websites that at one time hosted Wikipedia content, but no longer do. This should be checked periodically.
Problematic sites sometimes get listed on the mirror list without ending up here. So check the mirror list too: (Numbers) ABC DEF GHI JKL MNO PQR STU VWXYZ All
