FAQ: How can I find out if my source has a DOI number?

You can check to see if your item does have a DOI number by using the CrossRef.org This link opens in a new window website. However, not all electronic materials have digital object identifier numbers or DOI numbers.

You can search multiple ways by author, title and more but we recommend searching by the item's title. If you see the entry for your source and it lists the DOI, it has one and you are all set. If you search for your item and you do not see it listed, make sure you typed in the correct information, check your spelling...otherwise it is safe to assume there is no DOI number.
