WC

The prefix WC refers to:
 * webcasts (audio and/or video broadcasts) of Internet-exclusive material on licenced websites such as BBC.co.uk, primarily referring to original stories (i.e. Real Time, Scream of the Shalka)
 * webcast-original material which was later re-released in identical form to commercial media (i.e. Dead and Buried)

It does not refer to:
 * text stories or comics published exclusively online (i.e. 42 Prologue, The Return of the Vostok)
 * verbatim Internet rebroadcasts of existing video or audio stories; the appropriate non-WC prefix takes priority, even when
 * web-based e-books of text stories originally published elsewhere (i.e. PROSE: Lungbarrow) except when the citation is made to web-exclusive content which did not appear in the original version (i.e. File:Wolsey TARDIS console.png)
 * websites maintained by the BBC, as these are not valid sources
 * Water Closet
