This page in a nutshell: With the exceptions of short quotations from copyrighted text, and text copied from a free source without a copyright, text from other sources may not be copied into Wikipedia. Doing so is a copyright violation and constitutes plagiarism.

In most cases, you may not copy text from other sources into Wikipedia. Doing so is a

. Facts cannot be copyrighted. Titles of people or publications cannot be copyrighted. Text and illustrations prepared by the U.S. government are not copyrighted; they are in the public domain and can be used without permission, but to avoid plagiarism a citation is required indicating their source. Material from US states and local governments is copyrighted, as is material from foreign governments. Copyrights expire after many years and then the text becomes free.

As a general rule, do not copy text from other sources. Doing so usually constitutes both a

If I own the source, or work for the owner of the source, can I copy it to Wikipedia?

Generally no, unless the source is already under a license compatible with Wikipedia (such as

, however, Wikipedia can't retain it. Even if it is compatible, the content must comply with other content policies for us to be able to use it. Often, the tone and structure of the source itself might not be appropriate for an encyclopedia article, and most content on Wikipedia should be based on secondary, rather than primary, sources.

If you have published content on another user-generated website, they may have required you to grant them exclusive license, in which case you cannot contribute it here. Sometimes even when sites do not require exclusive license, such as IMDb, it may not be possible for you to use the content here as it may not be possible to verify that you are the individual who placed it there.

No. Superficial change of copyright-protected text is not enough. Wikipedia articles must be written in the author's own words. If the way in which a source has said something is important, please employ quotation.

No. While your user page and talk page may include brief quotations from copyrighted text, Wikipedia cannot host extensive copying of non-compatible copyrighted material anywhere, not even in talk or user pages, not even temporarily.

Brief quotations of copyrighted text may be used to illustrate a point, establish context, or attribute a point of view or idea. Use of copyrighted text must be in compliance with Wikipedia:Non-free content criteria policy. This means that the quotation must not be replaceable with free text (including text that the editor writes), must be minimal, must have contextual significance and must have previously been published.

Yes, you can copy parts of one Wikipedia article into another, but you must link to the source article in your edit summary. Original content contributed by users can be freely used if the original author is properly attributed. If you have copied text but forgotten to use the edit summary, this can be easily corrected: You can make a dummy edit by making an inconsequential change to the article—such as adding a blank line to the end of the article—and link to the source article in edit summary then. A note such as "content copied from [[source article]] on 1 January 2012" works fine.

It is also recommended to make a note on the talk page of the source article that copying has occurred, because the source article cannot be deleted as long as content from it is used. The template {{copied}} can be used for this as well as on the destination article's talk page.

It is acceptable to copy text from
