    "> In Epicpedia (2008), Annemieke van der Hoek creates a work that makes use of the underlying history that lies beneath the surface of each Wikipedia article.[20] Inspired by the work of Berthold Brecht and the notion of Epic Theater, Epicpedia presents Wikipedia articles as screenplays, where each edit becomes an utterance performed by a cast of characters (both major and minor) that takes place over a span of time, typically many years. The work uses the API of wikipedia to retrieve for a given article the sequence of revisions, their corresponding user handles, the summary message (that allows editors to describe the nature of their edit), and the timestamp to then produce a differential reading. \n",
