Wikipedia's Policy on the Reuse of Wikipedia Content

‎"Wikipedia: Reusing Wikipedia content

There are many reusers of Wikipedia's content, and more are welcome. If you want to use Wikipedia's text materials in your own books/articles/web sites or other publications, you can do so, but you must comply with one of the licenses that Wikipedia's text is licensed under. Many of the media files on Wikipedia are also reusable. Each media file has its own licensing statement which must be verified, and reuse of any media file must comply with its licensing.

Neither the Wikimedia Foundation nor the authors of material on Wikimedia sites provide legal advice. It is the responsibility of the reuser to determine how a license applies to the intended reuse." - http://en.wikipedia.org/wiki/Wikipedia:Reusing_Wikipedia_content

‎"Attribution—You must attribute the work in the manner specified by the author or licensor (but not in any way that suggests that they endorse you or your use of the work.)" - http://en.wikipedia.org/wiki/Wikipedia:CCBYSA

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 Wikipedia community. Text from external sources may attach additional attribution requirements to the work, which should be indicated on an article's face or on its talk page. 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." - http://en.wikipedia.org/wiki/Wikipedia:Reusing_Wikipedia_content#Re-use_of_text_under_Creative_Commons_Attribute_Share-Alike
