The Reference List is a list of all of the sources used in the research paper. Listed at the end of the research paper on a separate page, each reference entry includes the full bibliographic information (author, year, title, source) for each source. Carefully follow order, capitalization, punctuation, and font formatting. To create an accurate reference list entry, you will need to first determine the type of source you are working with (book, newspaper, blog, etc).
