A quick guide to APA referencing
APA style referencing is commonly used in the social and behavioural sciences. An APA reference consists of two elements:
- The in-text citation: A brief reference in brackets when you mention a source, citing the author’s last name and the year of publication, e.g. (Smith, 2019). It identifies the full source in the reference list.
- The reference list entry: Full publication details listed on the reference page, which appears at the end of your paper. The reference provides all the information needed to find the source, e.g. Smith, P. (2019, April 18). Citing Sources in APA Format. Retrieved April 21, 2019, from https://www.scribbr.com/apa-style/
This citation guide is based on the 6th edition of the APA Manual. The 7th edition, introduced in October 2019, is not yet supported, but we have compiled a quick guide to the most important changes.

Sorting the reference list
Sort the references in alphabetical order based on the author’s last name. If you are referencing multiple sources by the same author, then sort them by publication year.
