Presentations and Poster Sessions

Papers and poster sessions presented at meetings include both items that were presented but never published and items for which any subsequent publication is unknown. If subsequent publication is known, cite the published form rather than the meeting paper or poster session.

Begin the reference with information on the author(s) and title of the paper or poster session; use the same format as that used for conference papers.  Use the phrases "Paper presented at:" and "Poster session presented at:" to connect author and title information with meeting information.

Although author affiliation is an optional part of a citation, including it in references to unpublished papers and poster sessions is very helpful to the reader because compilations of papers and poster sessions can be difficult to locate.
