Permission to reproduce and modify text on Wikipedia has already been granted to anyone anywhere by the authors of individual articles as long as such reproduction and modification complies with licensing terms (see below and [[Wikipedia:Mirrors and forks]] for specific terms). Images may or may not permit reuse and modification; the conditions for reproduction of each image should be individually checked. The only exceptions are those cases in which editors have violated Wikipedia policy by uploading copyrighted material without authorization, or with copyright licensing terms which are incompatible with those Wikipedia authors have applied to the rest of Wikipedia content. While such material is present on Wikipedia (before it is detected and removed), it will be a copyright violation to copy it. For permission to use it, one must contact the owner of the copyright of the text or illustration in question; often, but not always, this will be the original author.

The licenses [[Wikipedia]] uses grant free access to our content in the same sense that [[free software]] is licensed freely. Wikipedia content can be copied, modified, and redistributed ''if and only if'' the copied version is made available on the same terms to others and acknowledgment of the authors of the Wikipedia article used is included (a link back to the article is generally thought to satisfy the attribution requirement; see below for more details). Copied Wikipedia content will therefore remain ''free'' under appropriate license and can continue to be used by anyone subject to certain restrictions, most of which aim to ensure that freedom. This principle is known as '''[[copyleft]]''' in contrast to typical copyright licenses.

== Contributors' rights and obligations ==

 

 

 

If the material, text or media, has been previously published and you wish to donate it to Wikipedia under appropriate license, you will need to verify copyright permission through one of our established procedures. See [[Wikipedia:Donating copyrighted materials]] for details. If you are not a copyright holder, you will still need to verify copyright permission; see the [[#Using copyrighted work from others|Using copyrighted work from others]] section below.

 

=== Using copyrighted work from others ===

 

 

'''Never''' use materials that infringe the copyrights of others. This could create legal liabilities and seriously hurt Wikipedia. If in doubt, write the content yourself, thereby creating a new copyrighted work which can be included in Wikipedia without trouble.

=== Linking to copyrighted works ===<!-- This section is linked from [[Wikipedia:WikiProject Albums]] -->

 

However, if you know or reasonably suspect that an external Web site is carrying a work in violation of the creator's copyright, do not link to that copy of the work. An example would be linking to a site hosting the lyrics of many popular songs without permission from their copyright holders. Knowingly and intentionally directing others to a site that violates copyright has been considered a form of [[Contributory copyright infringement|contributory infringement]] in the United States (''[[Intellectual Reserve v. Utah Lighthouse Ministry]]'' [http://www.law.uh.edu/faculty/cjoyce/copyright/release10/IntRes.html]). Linking to a page that illegally distributes someone else's work sheds a bad light on Wikipedia and its editors. The copyright status of [[Internet archive]]s in the United States is unclear, however. It is currently acceptable to link to internet archives such as [[Wikipedia:Using the Wayback Machine|the Wayback Machine]], which host unmodified archived copies of webpages taken at various points in time. In articles about a website, it is acceptable to include a link to that website even if there are possible copyright violations somewhere on the site.

If a page contains material which infringes copyright, that material – and the whole page, if there is no other material present – should be removed. See [[Wikipedia:Copyright violations]] for more information, and [[Wikipedia:Copyright problems#Instructions|Wikipedia:Copyright problems]] for detailed instructions.

 

 

Image description pages must be tagged with a special tag to indicate the legal status of the images, as described at [[Wikipedia:Image copyright tags]]. Untagged or incorrectly-tagged images will be deleted.

== Governing copyright law ==

{{More|Wikipedia:Non-U.S. copyrights}}

 

A brief summary of non-U.S. copyright laws, including guidelines on determining copyright status of the material in the United States, is available at [[Wikipedia:Non-U.S. copyrights]].

 

===Works by the United States Federal Government===

Works produced by civilian and military employees of the [[United States]] federal government in the scope of their employment are public domain by statute in the United States (though they may be protected by copyright outside the U.S.). It is not enough that the employee was working at the time; he/she must have made the work as part of his/her duties (e.g. a soldier who takes a photograph with his/her personal camera while on patrol in Iraq owns the copyright to the photo, but it may find its way onto a unit webpage or otherwise be licensed to the government).

 

Moreover, images and other media found on .mil and .gov websites may be using commercial [[stock photography]] owned by others. It may be useful to check the privacy and security notice of the website, but only with an email to the webmaster can you be confident that an image is in the public domain.

 

 

===Works by state governments of the United States===

 

== Reusers' rights and obligations ==

The only Wikipedia content you should contact the Wikimedia Foundation about is the trademarked Wikipedia/Wikimedia logos, which are not freely usable without permission (members of the media, see [[Foundation:Press room]], others see [[Wikipedia:Contact us]]). If you want to use other Wikipedia materials in your own books/articles/websites or other publications, you can do so, unless it is used under the [[WP:NFC|non-free content provisions]]—but only in compliance with the licensing terms. Please follow the guidelines below:

 

;Copyleft/Share Alike: If you make modifications or additions to the page you re-use, you must license them under the Creative Commons Attribution-Share-Alike License 3.0 or later.

;Indicate changes: If you make modifications or additions, you must indicate in a reasonable fashion that the original work has been modified. If you are re-using the page in a wiki, for example, indicating this in the page history is sufficient.

 

 

====Additional availability of text under the GNU Free Documentation License====

 

 

===Re-use of non-text media===

=== Non-free materials and special requirements ===

 

 

Prior to June 15, 2009, Wikipedia did permit some text under licenses that were compatible with the GFDL but might require additional terms that were not required for original Wikipedia text (such as including Invariant Sections, Front-Cover Texts, or Back-Cover Texts). However, these materials could only be placed if the original copyright holders did not require that they be carried forward; for that reason, they impose no special burden for reuse.

 

=={{anchor|owner}}If you are the owner of Wikipedia-hosted content being used without your permission==

'''If you are the owner of content that is being used on Wikipedia without your permission''', then you may request the page be immediately removed from Wikipedia; see [[Wikipedia:Request for immediate removal of copyright violation|Request for immediate removal of copyright violation]]. You can also contact our [[wikimedia:designated agent|designated agent]] to have it permanently removed (but it may take up to a week for the page to be deleted that way). You may also blank the page and replace it with the words <nowiki>{{copyvio|</nowiki>''URL or place you published the text''<nowiki>}}</nowiki> but the text will still be in the page history. Either way, we will, of course, need some evidence to support your claim of ownership.
