Professional, government agencies, and corporations often host conferences in which researchers can present new material and ideas to their peers. Conferences tend to be large multi-day events while a symposium is a smaller gathering, usually conducted in one day.
Using Proceedings in Research
Important current research is often presented at meetings and symposia, which is then published in periodicals, such as journals or even published in a book. These proceedings can be a good source for researching your school paper. It’s not difficult to cite published proceedings in APA format as it follows the book citation. You may also cite poster presentations the same way, if published.
Note: Include the URL or DOI, if retrieved online.
However, if the paper or presentation has not been published formally, use this format:
Contributor, A.A., Contributor, B.B., Contributor, C.C., & Contributor, D.D. (Year, Month). Title of contribution. In E.E. Chairperson (Chair). Title of symposium. Symposium conducted at the meeting of Organization Name, Location.
(Source: Publication Manual of the American Psychological Association)
Presenter, A.A. (Year, Month). Title of paper or poster. Paper or poster session presented at the meeting of Organization Name, Location.
Note: Use the month and year of the symposium or meeting for unpublished works.
It takes a little more work to find published and unpublished proceedings of symposia, poster and other presentations, but it gives depth to your research and provides current thought on ongoing research areas.
