Author. Title of source. Title of container, Other contributors, Version, Number, Publisher, Publication date, Location.
When the cited work is part of a larger work, e.g. an essay in a collection of essays, an article in a journal, an episode of a TV series, the larger work can be considered a container that holds the cited work. The title of the container is vital to the identification of the source.
Place the title of the container in italics, followed by a comma. The information that follows describes the cited work within the container (e.g. other contributors, volume, number, pages, etc).
For example, a journal article by Jo Royle was published in an online journal Publishing Research Quarterly:
Royle, Jo et al. "The Use of Branding by Trade Publishers: An Investigation into Marketing the Book as a Brand Name Product." Publishing Research Quarterly, vol. 15, no. 4, 1999, pp. 3-13, doi:10.1007/s12109-999-0031-1.
Containers within containers
You may have more than a single container for a source, e.g. an article published in a journal (container 1) that is available in a database of journals such as JSTOR (container 2); a single episode that is part of a TV series (container 1), which is available through a service such as Foxtel (container 2).
In the example below, an essay by Sarah Waldorf was published in a book of essays edited by Stephen W. Potts (container 1). which is available in a database EBSCOhost (container 2). The book is part of a series called Critical Insights (useful additional information but not crucial to the identification of the source - an optional element):
Waldorf, Sara. "A Turning Point in His Career: The Effect of the Hobbit on Middle-Earth." The Hobbit, edited by Stephen W. Potts, Salem; Grey House, 2016, pp. 145-159. Critical Insights EBSCOhost, search.ebscohost.com/login.aspx?direct=true&db=mzh&AN=2018580543&site=ehost-live.
