Create a spot-on reference in Chicago 18, 17 and 16
General rules
Both systems of Chicago Style (notes and bibliography and author-date) treat a conference paper published in conference proceedings as a chapter of a book, which is why the references for the two types of sources are quite similar. Use the following template to reference a conference abstract in a bibliography:
Author. Year of publication. "Paper Title." In Conference Proceedings Title, edited by Editor, pages. City of publication: Publisher.
The place and date of conference are not given in the reference.
For a conference paper available online, add the URL address at the end of the reference:
Author. Year of publication. "Paper Title." In Conference Proceedings Title, edited by Editor, pages. City of publication: Publisher. URL.
The date of access is given, if the date of publication is not stated in the source.
