Why use this guide?
The APA Guide by the Online Writing Lab (OWL) at Purdue University is used by hundreds of thousands of writers across the globe. They are well-liked for their clear examples of a variety of sources and how to cite them; e.g. websites with an author, websites with no author, webpages written by an organization, journal articles, book chapters, edited books, etc.
No matter what citation tool you are using – MyBib, Scrribr, RefWorks, etc. – it is a good idea to cross-check your in-text citations and reference list using the OWL Purdue lab examples. This will ensure correct citations.


"APA Style originated in 1929, when a group of psychologists, anthropologists, and business managers convened and sought to establish a simple set of procedures, or style guidelines, that would codify the many components of scientific writing to increase the ease of reading comprehension." - About APA Style
