General guidelines:

• The in-text citation consists of two main pieces of information: author surname(s) (this could also be an organisation), in the order that they appear on the actual publication, followed by the year of publication of the source that you are citing. Page number is needed for resources that include page numbers.
• The in-text citation is placed immediately after the information being cited. 
• If your citation is at the end of a sentence, ensure the full stop is placed after the reference.
• In-text citations are usually included in the word count of your document.
• For citations in brackets with two authors, the ‘&’ symbol is used. If the author citation forms part of your sentence the word ‘and’ must be used, e.g., (Brown & Black, 2010) OR Brown and Black (2010) indicate that…
• For citations with 3 - 20 authors, use the first author's surname followed by et al. Always put a full stop after the al. in et al., because it is short for "et alia" ("and others").
• A page number is required for both direct quotes and paraphrasing, if a resource contains page numbers (e.g. when quoting or paraphrasing from books or journal articles). Only if you refer to a source as a whole (e.g. a book), no page number is needed. To enter pages: single page: p. 25, multiple pages: pp. 25-26, discontinuous pages: pp. 25, 31. 
• Do not include month or date for an in-text reference, even if this information is included in the reference list.
• If there is no date, the abbreviation n.d. may be used (Harris, n.d.).
• To directly quote from online material without pagination, name the major sections (chapter, section, and paragraph number; abbreviate if titles are long). See the example at the bottom of this page.
