The Reference Page
When referencing a webinar, you must cite it on the reference page in the following manner:
Author Last Name, First Initial. Second Initial. (Year, Month Day). Title of webinar [Webinar]. In Company Webinar Series. Retrieved from URL.
Here is an example: O'Leary, D. (2013, May 8). The Medical Device Excise Tax -- Are You Ready? [Webinar]. In Elsevier Business Intelligence Webinar Series (italics). Retrieved from http://www.elsevierbi.com/mkt/Webinars/AC/AC050813LP.
Note that the name of the company needs to be italicized.
When discussing the webinar within the body of your paper, you must include a parenthetical citation, like so: (Author last name, year). For the given example, the in-text citation will look like this: (O'Leary, 2013).
