As far as possible, cite audiovisual material in the same way as you would cite a book. Include details of the format of the material, e.g. video, DVD, CD-ROM, audiocassette, compact disc.
Examples:
1. Winfried Scharlau and Ming Shi, The Unfortunate Generation: Cultural Revolution and Beyond, directed by Ralph Quinke (Princeton: Films for the Humanities & Sciences, 2004), DVD.
2. Mike Dewitt and Daniel Jonah Goldhagen, Worse Than War, produced and directed by Mike Dewitt (JTN Productions and WNET.ORG, 2009), video, http://www.youtube.com/watch?v=w7cZuhqSzzc.
