What is a DOI Number and how do I find it?
Answer
A DOI (Digital Object Identifier) is a unique alphanumeric identifier assigned to a digital object by a registration agency (the International DOI Foundation). The number helps identify digital content. Many journal publishers are assigning DOIs to electronic copies of articles they publish. However, not all digital content has a DOI.
How to find if an article has a DOI
- Look at the article. If a journal a publisher assigns a DOI number, it will usually be printed somewhere on the first page.
- You can also search for the DOI number using Crossref or PubMed
