Don't start me wondering why, with the search string ... example of YouTube video referenced in academic paper... google gave me Dan Calladine's blog post (2009, Feb 6) about "the best set of YouTube Annotations videos [he's] ever seen".
Sure have some fun with the game (BENandERIC, 2008, November 7) yourself AFTER you tell me where you've seen a paper citing a YouTube video (please because playing the game will take you away from here).
I'm actually looking for new YouTube videos to practice referencing, particularly ones that have
(a) no discernible statement of responsibility (author/creator/producer), so the reference will begin with the video title; or at the other end of the scale
(b) a place and "publisher/distributor" to include in the reference.
The video cited here allowed for additional examples of citing a screen-name, a practice endorsed by APA (2007, p23).
