In-text citations are included throughout the course of your writing, to acknowledge the sources of information you have used to build and support your ideas.

Palladino and Wade (2010) argue that mental well-being is linked with flexible thinking.
It could be argued that mental flexibility is a key factor in well-being (Palladino and Wade 2010).
Quoting is when you copy the exact words (including spelling and punctuation) from another source into your work.

In fact, “a flexible mind is a healthy mind” (Palladino and Wade 2010, 147).
Lee (2015, para. 1) states that “double quotation marks are used to enclose quoted material.”
“In the APA and Chicago referencing styles, double quotation marks are used to enclose quoted material” (Lee 2015, para. 1).

The function of any citation-signaller is to alert the reader to some kind of association between the citing text and the cited text. Citation-signallers may additionally, by using page references or chapter numbers, single out a particular part of the text as especially relevant. (Langham 2005, 361)
When including multiple sources to support a particular point in your writing or demonstrating a consensus:
Multiple sources example
