An author-date citation in running text or at the end of a block quotation consists of the last name of the author, followed by the year of publication of the work in question. No punctuation appears between author and date. Abbreviations such as ed. are omitted. Author-date citations must agree exactly, in both name and date, with the corresponding entries in the reference list, and there must be an entry for every text citation.
(Steven and Gunaratna 2004)
When a specific page is cited, it follows the date, preceded by a comma.
(Gourévitch 2006, 57)
Author-date citations are usually placed just before a mark of punctuation.
A reference list is normally placed at the end of a work, preceding the index, if there is one. Because the text citations consists of the last name of the author and the date of publication, a reference list is always arranged alphabetically, rarely divided into sections, and the date of publication appears directly after the name.
