Citation Tips

What is a DOI? A DOI (digital object identifier) is a unique alphanumeric string assigned by a registration agency (the International DOI Foundation) to identify content and provide a persistent link to its location on the internet.  Used for both print and electronic sources.

Use DOI instead of the URL link (see 3.11.4): When possible, use the DOI instead of the URL.

Year, Volume, Issue, Location (Page Numbers), and Dates (see 3.11.3): No spaces in between
