How do I cite the same author twice?
If you are using 2 different sources from the same author, there are two possible ways to cite this, depending on if the sources were published in the same year or different years.
- If you have two works by the same author, but with different years, you will not need to differentiate them using letters because the publication year will indicate which resource you are making reference to. For example, you might have (Jones, 2010, p. 37) and (Jones, 2012, p. 301). There will be no change to your reference in the references section of your paper either.
- To cite two works by the same author and the same year in an in text citation, you will differentiate the two works with small lowercase letters. For example, you could write (Smith, 2009a, p. 78) and (Smith, 2009b, p. 24). On the references page, you should sort the two entries in alphabetical order by the title of each article, since the authors' names will be identical. You should designate each entry with the same small lowercase letters you use in your in-text citations. For example:
Smith, J. (2009a). Rise and fall of management systems. New York, NY: Wiley.
Smith, J. (2009b). Systems Management. Chicago, IL: Hawthorne Press.
