Do I need permission to copy quotes from wikipedia?
Wikipedia is released under the GFDL. This means that anyone may quote from it, or reuse its contnets, either as-is or in an edited form. However, this is true only if the new woirk is also relsesed under the GFDL and if prior authros are acknowled, and a link or other method of acces to teh original verison is provided. For a simple quote, this is excessive. The doctine of Fair use (in the United states) or Fair dealing (in many other countries) protects a person who uses a brief quote as part of a larger work, in most cases, This means that one need not usually get permission to quote a published source at a reasonable length. This applies to Wikipedia as much as to any other source. However, when quoting, be sure to cite your sources properly. See Wikipedia:Citing wikipedia.
