Wikipedia:Plagiarism/Plagiarism problems

This page is for listing and discussing possible plagiarism problems involving text on Wikipedia. For pages which are suspected to be copyright violations, see Wikipedia:Copyright problems.

Authors of material

If you believe Wikipedia is infringing your copyright, you may request immediate removal of the copyright violation or you may contact Wikipedia's designated agent under the terms of the Online Copyright Infringement Liability Limitation Act. See also Wikipedia:Copyright problems

If you believe there is not copyright violation, or that whether copyright violation has occurred is in a gray area, but that your ideas or words are not attributed properly, please post here.

What is plagiarism in wikipedia

Plagiarism in Wikipedia is the use of ideas and/or wording with less attribution than is reasonably expected to be provided. Some cases are clearly plagiarism, as when a long passage is copied verbatim into Wikipedia from some other source, without giving credit to the original writers or that source in any way. (It may further be copyright violation, if the source is copyrighted, but this problems area is to deal with under-attribution of public domain, GFDL or other text where copyright issues are not present.) Other cases are a matter of judgement. Guidance is provided in Wikipedia:Plagiarism, which is a relatively new but official Wikipedia guideline.

Plagiarism that does not infringe copyright

Wikipedia will naturally refer to and include some material that comes from outside sources. This material may be in the public domain, may be included under a fair use argument, or it may be under a license compatible with the license used on Wikipedia, the GNU Free Documentation License (GFDL). Examples of public-domain works include text and images from United States Government publications, and older works—such as the 1911 Encyclopædia Britannica—that are no longer, or never were, covered by copyright. Some further examples are at Category:Attribution templates.

Even when material is not covered by copyright, it is still important to state its origin, including its authors or creators. Failure to include the origin of a work is misleading and also makes it more difficult for readers and editors to refer to the material's source. It may also violate the terms of the GFDL.

Material that is plagiarised but which does not violate copyright does not need to be removed from Wikipedia if it can be properly sourced. Add appropriate source information to the article wherever possible, or move unsourced material to an article's talk page until sources can be found.

If an editor has copied text or figures into Wikipedia without proper attribution, politely refer him to Wikipedia:Verifiability, Wikipedia:Citing sources, and/or Help:Citations quick reference. Editors who have difficulties or questions about this guidance can be referred to the Help Desk. Editors engaged in ongoing plagiarism who do not respond to polite requests may be blocked from editing.

Repeated plagiarism violations

Contributors who repeatedly post material that violates attribution guidelines (and constitutes plagiarism) after appropriate warnings will be blocked from editing to protect the project. (Copyright violaters have been blocked; the plagiarism guideline is new and has not yet directly led directly to any such blocks, although plagiarism may have been discussed and used as reason for blocking in other cases before this guideline was formally expressed.)

Instructions

Material whose presence on Wikipedia appears to constitute plagiarism (i.e. the material is not sourced with footnotes, verbatim passages are not put into quotes or blockquotes) should, as a general rule, be revised to provide adequate attribution for the ideas and wording, or removed.

{{db-copyvio | describe non-web source here}}

An administrator will examine the article and decide whether to delete it or not. You should not blank the page in this instance. }}

If infringement is not blatant or the speedy deletion criteria do not apply: Revert the page to a non-copyrighted version if you can The infringing text will remain in the page history for archival reasons unless the copyright holder asks the Wikimedia Foundation to remove it. Please note the reason for removal in edit summary and at the article's talk page (you may wish to use {{cclean}}). However, if all revisions have copyright problems: Place on the page one of the following: {{subst:copyvio | url=insert URL here}} {{subst:copyvio | identify non-web source here}} This will blank all text beneath the template. (To limit blanking, place </div> at the end of the text to be blanked.) Go to today's section and add * {{subst:article-cv | PageName}} from [insert URL or identify non-web source here] ~~~~ to the bottom of the list. Put the page's name in place of "PageName". If you do not have a URL, enter a description of the source. (This text can be copied from the top of the template after substituting it and the page name and url will be filled for you) Advise the contributor of the material at his or talk page. The template on the now blanked page supplies a notice you may use for that purpose. You're done!

Instructions for special cases

• Probable copyvios without a known source: If you suspect that an article contains a copyright violation, but you cannot find a source for the violation (so you can't be sure that it's a violation), do not list it here. Instead, place {{cv-unsure|~~~|2=FULL_URL}} on the article's talk page, but replace FULL_URL with the full URL of the article version that you believe contains a violation. (To determine the URL, click on "Permanent link" in the toolbox area, and copy the URL.)

Alternatives to deletion

In addition to nominating potential copyright infringements for deletion, you may:

• Rewrite the article, excluding copyrighted text. This is done on a temporary page at Talk:PAGENAME/Temp so that the original, copyright-infringing version can be deleted by an administrator and the rewrite copied over. If the original turns out to be non-infringing, these two can be merged.
• Write to the owner and ask for permission. Check whether they gave or will give permission (or maybe they in fact posted it here!). Also see Wikipedia:Example requests for permission, Wikipedia:Confirmation of permission.
• Where appropriate, please address the matter with the contributor who added the infringement. {{copyvio}} and {{db-g12}}, for speedy deletions, will generate a notice that you can paste on the contributor's page. Other notices can be found at Category:Wikipedia copyright maintenance templates.

Instructions for administrators

Pages should stay listed for a minimum of 7 days before they are checked and processed by administrators. See Wikipedia:Copyright problems/Advice for admins for some help.

All pages tagged with {{copyvio}} are placed in Category:Possible copyright violations.
