One of the most important aspects of Wikipedia is that its text (not media; but we will get to that) may be freely redistributed, reused and built upon by anyone, under the terms of the Creative Commons Attribution-Sharealike 3.0 Unported License (CC-BY-SA) and, except where otherwise noted, the GNU Free Documentation License (GFDL) (unversioned, with no invariant sections, front-cover texts, or back-cover texts). Contributors agree to release their original content under both licenses when they submit it, and material from public domain sources or other compatibly-licensed sources may also be used in accordance with the copyright policy, provided correct attribution is given.

However, material copied from sources that are not public domain or compatibly licensed without the permission of the copyright holder (unless brief quotation used in accordance with non-free content policy and guideline) is likely to be a copyright violation. Such a situation should be treated seriously, as copyright violations not only harm Wikipedia's redistributability, but also create legal issues.

The situation for images and other media is slightly different, as a wider variety of licenses is accepted. But, in short, media which is not available under a suitable free license and which does not meet the non-free content criteria, should be assumed to be unacceptable. See Wikipedia:Image use policy and Wikipedia:Non-free content for details of this.

Dealing with copyright violations[সম্পাদনা]

Contributors who repeatedly post copyrighted material despite appropriate warnings may be blocked from editing by any administrator to prevent further problems. Contributors who have extensively violated copyright policy by uploading many copyrighted files or placing copyrighted text into numerous articles may be blocked without warning for the protection of the project, pending satisfactory assurances that infringement will not continue. In extreme cases administrators may impose special conditions before unblocking, such as requiring assistance with cleanup by disclosing which sources were used. If contributors have been shown to have a history of extensive copyright violation, it may be assumed without further evidence that all of their major contributions are copyright violations, and they may be removed indiscriminately.

If you suspect a copyright violation, you should at least bring up the issue on that page's discussion page. Others can then examine the situation and take action if needed. The most helpful piece of information you can provide is a URL or other reference to what you believe may be the source of the text.

Some cases will be false alarms. For example, if the contributor is the copyright holder of the text, then even if it is published elsewhere under different terms, they have the right to post it here under CC-BY-SA and GFDL – the text may still be unsuitable for Wikipedia for another reason, but it is not a copyright violation. They may donate the material through the procedures described at Wikipedia:Donating copyrighted materials. Text that can be found elsewhere on the Web that was in fact copied from Wikipedia in the first place is also not a copyright violation – at least not on Wikipedia's part. In both these cases, it is a good idea to make a note of the situation on the discussion page.

If some, but not all, of the content of a page appears to be a copyright infringement, then the infringing content should be removed, and a note to that effect should be made on the discussion page, along with the original source, if known. If the copyright holder's permission is later obtained, the text may be restored.

If all of the content of a page appears to be a copyright infringement, check the page history; if an older non-infringing version of the page exists, you should revert the page to that version.

If there is no such older version, you may be able to re-write the page from scratch or obtain permission from the copyright holder (see Wikipedia:Requesting copyright permission), but failing that, the page will normally need to be deleted. In limited circumstances, administrators may delete obvious copyright violations on sight; see the relevant section of the speedy deletion policy. Contributors may list pages that meet these conditions for deletion using the {{db-copyvio}} tag.

If the criteria for speedy deletion do not apply, you should replace the contents of the page with the {{subst:copyvio | url=insert URL here}} tag, and list the page at Wikipedia:Copyright problems; see instructions. If, after a week, the page still appears to be a copyright infringement, it may be deleted by any administrator.

Copyright owners[সম্পাদনা]

If you are a copyright owner or represent a copyright owner, and you believe that Wikipedia is infringing your copyright, we can assist you best via e-mail. You may contact info-en-cAt sign.svgwikimedia.org with an informal request; please cite the exact URL (the "address" or "location" of the page as shown by your web browser, beginning with http://en.wikipedia.org/...), and provide enough information to substantiate your claim of copyright ownership. Be aware that correspondence is answered by a small number of volunteers, and an immediate reply may not be possible.

If you prefer to use the slower process of a formal OCILLA request, you should send it to the Wikimedia Foundation's designated agent.
