A DOI, or digital object identifier, is a unique identifier which provides a permanent link to an article's location on the Internet. All DOI numbers begin with a 10 and contain a prefix and a suffix separated by a slash. It might look like this doi: 10.00000/000000000000 or http://dx.doi.org/10.0000/0000.

The DOI, when available, can be found:

  • On the first page of an e-journal article (often near the copyright notice)
  • In the database record for an article
  • From an Internet search for the journal. Sometimes the journal's website will have the DOI.

You can see if an article has a DOI by searching CrossRef, the official DOI Registration Agency of the International DOI Foundation.

Not all articles have DOIs. Articles published prior to 2000 are less likely to have DOIs. Also, not all publishers will be registered for the DOI system so bear this in mind.

If you know the DOI of an article the quickest way to access it in the University’s Electronic Library is to click on the Go to an Article then enter the DOI in the search box on the left ( 'Go to an Article - DOI known' ). This will retrieve both articles fully published and ahead of print if the latter have had DOI numbers already assigned. If you cannot locate a DOI then use 'Go to an Article - journal, vol, page, year known' and enter the details of the article you have located.
