An author-date citation in the text or at the end of a block quotation consists of the surname of the author, followed by the year of publication of the work in question. There is no punctuation between the author and the date. Abbreviations such as ed. are omitted. Author-date citations must match exactly, both in name and date, with the corresponding entries in the reference list, and there must be an entry for each textual 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 punctuation mark.
A reference list is usually placed at the end of a work, before the index, if there is one. Since text citations consist of the author's surname and the date of publication, a reference list is always alphabetical, rarely divided into sections, and the date of publication appears immediately after the name.
