Conference proceedings are a great way to stay up-to-date on the latest research in your field. When you reference conference proceedings in Harvard style, you need to include the author, title, conference name and location, and date. You also need to include the page numbers for the specific article or chapter you are referencing.

If you are referencing an unpublished conference paper, you will need to include more information about the conference itself. For example:
