| | Wikimedia Commons - Wikipedia, the free encyclopedia |
 | | A key motivation behind the setup of a central repository was a desire to reduce duplication of effort across the Wikimedia projects and languages, as the same file had to be uploaded to many different wikis separately before the Commons was created. |
 | | The possibility of local uploads still exists, but is meant to be used primarily for material which local project policies allow, but which would not be permitted according to the licensing policy of the Commons, such as fair use content. |
 | | As of 2006, the Wikimedia Commons itself does not allow fair use or uploads under non-free licenses, including licenses which restrict commercial use of materials or disallow derivative works. |
