Publication Format

The format of the reference being cited—for example, print, online, video, audio, etc. This attribute should be used when known.


The @publication-type, @publisher-type, and @publication-format attributes replace the citation-type attribute of prior versions, which provided no clear way to distinguish these different notions.
