DOI: Digital Object Identifier

The DOI is a set of numbers and/or letters given to individual journal articles.

  • You should include the DOI for articles retrieved online or from hardcopy

  • The database might give the DOI in the citation section. If not, then you may find it at the top or bottom of the first page

  • When you have a DOI, you do not need to include the web address

  • When you do not have a DOI, you must include the URL of the journal's homepage from the publisher's website. If this URL is too long, you may use the publisher's
    homepage. You may have to search for this website online.

    Do not use the direct URL of the article and do not use the database name or URL
    (exceptions; a dissertation, an ERIC document or older JSTOR article)

  • Older hardcopy journals will not have a DOI, so you will cite it without one
