how to reference a reference in a journal article

In their review of the literature (Knapik et al., 2015)…

• Author (surname followed by initials).
• Year of publication (in round brackets).
• Title of article (in single quotation marks).
• Title of journal (in italics).
• Issue information – volume (unbracketed) and, where  applicable, part number, month or season (all in round brackets).
• Page reference.
• doi (if available).

Sometimes an author writes about research that someone else has done, but you are unable to track down the original research document. In this case, only include the source you did consult in your references because you did not read the original document. Use the words ‘cited in’ in the in-text citation to indicate you have not read the original research.

Example 2 Journal article

Note: Minimal capitalisation is recommended for the titles of articles; maximal capitalisation is conventionally used for journal titles. See examples below.
Author(s) of journal article – family name and initials Year of publication, ‘Title of journal article – in single quotation marks’, Title of Journal – italicised, Volume, Issue or number, Page number(s).

Your in-text citation should include both authors: the author(s) of the original source and the author(s) of the secondary source. For example: (Habermehl, 1985, as cited in Kersten, 1987).
In your reference list you should provide the details of the secondary source (the source you read). In this example: the details of Kersten 1987.
