|A DOI (digital object identifier) is a unique alphanumeric string assigned by the International DOI Foundation to identify content and provide a persistent link to its location on the Internet. The publisher assigns a DOI when the article is published and made available electronically.|
DOI numbers start with a 10 followed by a full stop and contain a prefix and a suffix separated by a slash. The prefix is a unique number of four or more digits assigned to organizations; the suffix is assigned by the publisher and was designed to be flexible with publisher identification standards. The format for DOI in your references: doi:10.xxxx/xxxxx
Some referencing styles recommend that when DOIs are available you should include them in your citations.
Here is an example of a DOI:

DOIs are usually located:
1. on the first page (abstract page) of the electronic journal article, near the copyright notice or near the author's address.
2. on the database landing page in the Full Record Display of the article with the field labelled DOI.
3. on the PDF version of an article DOIs will be located on the cover sheet, towards the top or the bottom of the article.
