At the end of your essay, place a list of the references you have cited in the text. Arrange this in alphabetical order of authors' surnames, and then chronologically (earliest publication date first) for each author where more than one work by that author is cited. The author's surname is placed first, followed by initials or first name, and then the year of publication is given. If the list contains more than one item published by the same author(s) in the same year, add lower case letters immediately after the year to distinguish them (. 1983a). These are ordered alphabetically by title disregarding any initial articles ( a , an or the ).
