What are DOIs?

Crossref.org
Look up DOI's and learn more about DOI's for research content.

Instead of long URL's and permalinks, citation styles such as APA now use DOI's or Digital Object Identifiers. They provide a stable place to retrieve documents.

When a DOI number is available use this format in references (example) https://doi.org/10.5555/12345678
Create a URL to a document by adding the DOI number at the end of https://doi.org/
If the document doesn't have a DOI, use the permalink.
