This should only be used when the author or group of authors is identical, and where the year of publication is the same.
If an author has worked with two colleagues to produce two articles in the same year but those two co-authors are different for each article, you do not need to do this.
When an author, corporate author, editor or group of authors/editors, has more than one publication in the same year, you should add a lower case letter to the date in your reference, for example:
Harding, S. (1986a). The instability of the analytical categories of feminist theory. Signs, 11(4), 645-664.
Harding, S. (1986b). The science question in feminism. Cornell University Press.
If you are using multiple sources without a publication date by the same author, you can do the same thing but with (n.d.) In this instance you should include a dash before the lower case letter. It would look like this: (n.d.-a)
When arranging these sources in your reference list, you should do so alphabetically by title, disregarding the words 'A', 'An' or 'The' at the beginning.
If the title starts with a number, you should treat this as if it was spelled out for the purposes of order, but retain the original spelling in the reference. For example, '20' would be treated as if it said 'twenty'.
