Online articles sometimes change their Web addresses (URL). Many style formats recommend that you cite a Digital Object Identifier (DOI) to identify an article, rather than the URL.
DOI’s attempt a stable link for online articles. Every DOI is unique to a specific document and consists of code made up of numbers and letters.
- Not every publisher will assign DOI numbers to articles. Many articles don’t have a DOI number.
- Older articles in particular may not have a DOI number.
- Some article databases provide a DOI number, but not all.
If you can’t find the DOI for an article, you can look it up using this free service: Crossref.org
Once I have the DOI, how do I find the article online?
- The following free service will create a URL from your DOI Number: DOI.org
- This allows you to find the article online. Be aware that many articles may only be viewed and downloaded by TWU students and faculty using your Portal username and password.
