Guidelines

Information for re-users

You can re-use content from Wikimedia projects freely, with the exception of content that is used under "fair use" exemptions, or similar exemptions of copyright law. Please follow the guidelines below:

Re-use of text:

• Attribution: To re-distribute a text page in any form, provide credit to the authors either by including a) a hyperlink (where possible) or URL to the page or pages you are re-using, b) a hyperlink (where possible) or URL to an alternative, stable online copy which is freely accessible, which conforms with the license, and which provides credit to the authors in a manner equivalent to the credit given on this website, or c) a list of all authors. (Any list of authors may be filtered to exclude very small or irrelevant contributions.) This applies to text developed by the Wikimedia community. Text from external sources may attach additional attribution requirements to the work, which we will strive to indicate clearly to you. For example, a page may have a banner or other notation indicating that some or all of its content was originally published somewhere else. Where such notations are visible in the page itself, they should generally be preserved by re-users.

• 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.

• Licensing notice: Each copy or modified version that you distribute must include a licensing notice stating that the work is released under CC-BY-SA and either a) a hyperlink or URL to the text of the license or b) a copy of the license. For this purpose, a suitable URL is: http://creativecommons.org/licenses/by-sa/3.0/

• For further information, please refer to the legal code of the CC-BY-SA License.

Additional availability of text under the GNU Free Documentation License:

• For compatibility reasons, any page which does not incorporate text that is exclusively available under CC-BY-SA or a CC-BY-SA-compatible license is also available under the terms of the GNU Free Documentation License. In order to determine whether a page is available under the GFDL, review the page footer, page history, and discussion page for attribution of single-licensed content that is not GFDL-compatible. All text published before June 15th, 2009 was released under the GFDL, and you may also use the page history to retrieve content published before that date to ensure GFDL compatibility.

Re-use of non-text media:

• Where not otherwise noted, non-text media files are available under various free culture licenses, consistent with the Wikimedia Foundation Licensing Policy. Please view the media description page for details about the license of any specific media file.
