About APA Style

There are two parts to referencing: the citations within the text of your paper and the reference list at the end of your paper.

The APA referencing style is an "author-date" style, so the citation in the text consists of the author(s) and year of publication given wholly or partly in round brackets.

Use only the surname of the author(s) followed by a comma and the year of publication. Include page, chapter or section numbers if you need to be specific, for example if you are quoting, paraphrasing or summarising:


No distinction is made between books, journal articles, internet documents or other formats except for electronic documents that do not provide page numbers. In this case use the paragraph number, if available, with the abbreviation para.

The full details of the source are given in a reference list at the end of the document:


Reference list entries contain all the information that is required to follow up your source. Reference lists in APA are arranged alphabetically by author.

See Reference List Entries or All Examples for details on how to construct references for specific resources such as books, journals and web pages.
