Your university should tell you which referencing style to follow. For works with two authors include both names in alphabetical order. Call number, Box number, File name or number, etc. The contributions of others who appear in the video may be included in the text narrative if desired. Cite only the surname of the first author followed by et al. Yes, our editors also work during the weekends and holidays. When Do I Need to Cite a Source?
