Wikiquote is one of a family of wiki-based projects run by the Wikimedia Foundation, running on MediaWiki software. Based on an idea by Daniel Alston and implemented by Brion Vibber, the goal of the project is to produce collaboratively a vast reference of quotations from prominent people, books, films and proverbs, and to give details about them. Though there are many online collections of quotations, Wikiquote is distinguished by being among the few that provide an opportunity for visitors to contribute. Wikiquote pages are cross-linked to articles about the notable personalities on Wikipedia.
