Exploring the Markup for Bibliographies in OpenXML WordprocessingML

I’ve received a couple of questions recently about bibliographies. I sat down to write a blog post about it, and then realized it would benefit from a screen-cast that explains the markup. The following screen-cast walks through bibliography markup. Bibliographies use custom XML parts, so in addition to showing the field markup for citations and the generated bibliography, the screen-cast discusses the mechanism by which you can determine the purpose of any particular custom XML part. Because a WordprocessingML document could potentially contain more than one variety of custom XML parts, it is important to write your code in such a way that you correctly identify the custom XML part that you are interested in.
