The instructions in this section concern references to articles in scientific journals. Note that if the article is published in an online journal, it might have been provided with an article number or eLocator instead of page numbers. In that case, state the article number or eLocator preceded by the word “Article” in place of the pages at the end of the reference.

If a DOI has been assigned to the article, include this number in the reference. If no DOI has been assigned and the article was accessed online from a nondatabase website, use the URL of the webpage from which it was retrieved. If the article was accessed in print or retrieved from an academic database, no URL is included.

Some articles will have supplementary information in the online version, which is material related to the article that could not be included in the printed version for reasons of space or medium (e.g. video or sound files). The material is often in the form of tables or figures, but it could also be text (sometimes in a separate document). The supplement may or may not be peer reviewed. If you want to cite supplementary information from an article, consult with your teacher/supervisor whether or not the material is an appropriate source. For advice on how to format references to supplementary information, ask your librarian.

Do not forget to consult the general instructions on how to write references according to APA (7th edition), including
