What IEEE includes

These are the details of the example above that the style prints, so they are the ones to collect for your own source.

  • Entry Title
  • Author(s)
  • Encyclopedia
  • Publisher
  • Date Published
  • URL
  • Date Accessed

Take the entry’s title, and its author if it names one, from the article, and the editors, edition and publisher from the encyclopedia’s title page or about page. Online, link to a fixed version if there is one, such as a Wikipedia permanent link or an archived edition of the Stanford Encyclopedia of Philosophy, and give its date. There is no box for a volume, so add one by hand if your style asks for it.

The formatting comes from the style's own file, so check the finer points against your guide. What to check by hand in IEEE.
