Citations allow you to track and document where the information you've used in your research came from and to give other scholars/artists credit for their original work. These are some common situations that require citations:
From the Purdue OWL:
A bibliography is a list of sources (books, journals, Web sites, periodicals, etc.) one has used for researching a topic. Bibliographies are sometimes called "References" or "Works Cited" depending on the style format you are using. A bibliography usually just includes the bibliographic information (i.e., the author, title, publisher, etc.).
An annotation is a summary and/or evaluation. Therefore, an annotated bibliography includes a summary and/or evaluation of each of the sources.

Dance DVD or VHS
Citations for film or video recordings usually begin with the title of the film:
Title. Director, choreographer, relevant performers (if any). Distributor, date. Format.
However, if you’re citing the contribution of a particular individual, like a choreographer, you can begin with that person’s name. For example:
Jones, Bill T. Still Here. Dir. Alice Markowitz. Films for the Humanities and Sciences,1997. VHS.
Dance videos found online, such as through UbuWeb or On the Boards
If the online work you are citing was not born digital (i.e., is a digitized version of a film or live performance), begin your citation by following MLA’s citation recommendations for the original format. Conclude your citation with:
1. Title of the website (italicized)
2. Medium of publication (Web)
3. Date of access
It’s still ok to begin your citation with the name of the choreographer, if that is the individual whose contribution you are citing. For example:
Jones, Bill T. and Arnie Zane. “Rotary Action.” Alive From Off Center. PBS. 15 July 1985. UbuWeb. Web. 13 November 2013.
