References to unpublished material may include articles or abstracts that have been presented at a society meeting and published as part of the meeting proceedings or materials.
UPDATE: Guidance has been added to chapter 3.13.9.1, Items Presented at a Meeting, to provide an example of how to cite materials from a virtual or hybrid meeting. This addition was made May 26, 2022.
Oral or poster presentations follow these formats. Note that example 4 is a virtual meeting. Hybrid meetings can list the location, the meeting URL, both, or neither depending on what information is available and how the author viewed the content.
