APA referencing is based on an author-date system. Sources are listed by the author's surname (family name) and by the year the source was published.
Citation format changes according to the number of authors there are for a source and for the type of source referenced. For example, a journal article citation is formatted differently than a book citation. This difference is obvious only on the "References" page. Citations in the body of your paper use only author and date. This guide provides information for citation format in papers and on the references page.
The following are examples of different citation formats for a source by one author.
In the Body of Your Paper
Narrative citation (beginning of sentence): Bunker (2014) cautions that not all monitors provide accurate measurements of BP.
Parenthetical citation (end of sentence): Some monitors provide more accurate measurements of BP than others (Bunker, 2014).
