Doom Wiki:Copyrights

All text on the Doom Wiki is freely licensed under the terms of the GNU Free Documentation License (GFDL).

Anything which looks like plagiarism will be removed unless the editor has obtained written permission (e-mail is acceptable) and posts it to the article's talk page.

Image copyrights are more complex (as is well known on Wikipedia), and Doom Wiki does not pretend to be an authority on copyright law. Currently our policy is that: Other types of images are discussed on a case-by-case basis (see our image uploading policy).
 * Screen shots of commercially released games can be used under "fair use".
 * Screen shots of PWADs can be used under "fair use" as long as the content of the maps themselves is original.
 * Map views extracted from WADs can be used under "fair use", provided they contain no raw graphics lumps.
 * LMPs and PWADs, when uploaded by their creator, can be licensed under the GFDL provided that no incompatible license is already in place.
