  • If a final version of an article is being referenced there is no need for a retrieval date.
  • If a DOI is given, there is no need to include a database name or URL.
  • If no DOI is given, give the exact URL, or the URL of the journal home page if the content is accessible by subscription
  • Use “Available from” instead of “Retrieved from” when the URL leads to information on how to obtain the material rather than to the material itself.
  • Include the database name for e-books to aid readers in finding the electronic version.
