An in-text citation provides information about the author, the year the information was published, and sometimes location information such as a page number.

In-text citations are important in academic writing, drawing the parallel between the author’s work and the sources which support it:
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 citing a secondary source:
…“event in nature or in society” (Blaikie et al. 1994, as quoted by Maldonado et al. 2013, 602).
