How is referencing done?

There are many styles of referencing seen in academic sources that you may be using, but all have at least two components:

  1. An indication in the main text when the words or ideas of another have been used.
  2. A list of references, giving complete publication details of the sources of borrowed information.

There are basically two systems of referencing: Author–date systems and Note systems.

Author–date systems

  • give the family name of the author(s), the year of publication and page numbers if necessary, after the relevant text in the main body of the document
  • provide a reference list with full publication details of every source cited in the document.

Example using American Psychological Association (APA) author-date system:

Collins (2002, p. 2) refers to this as “the inevitable conflict”.


This has been referred to as “the inevitable conflict” (Collins, 2002, p. 2).

Note systems:

  • use a superscript number in the main text to indicate where information has been used from another source
  • provide footnotes at the bottom of each page, or a list of endnotes at the end of the document, giving full publication details of every source cited in the document
  • often also include a bibliography in alphabetical order according to the author's family name.

Example using Turabian (notes-bibliography) system:

Collins refers to this as 'the inevitable conflict'.1
