DOI numbers are important both for citing articles in APA citation format and for retrieving articles online. Read more about DOI numbers below.
What is a DOI Number?
DOI stands for digital object identifier. DOI numbers can be assigned to almost anything—books, videos, images—but you will see them primarily on academic journal articles. The purpose of a DOI number is to make an item more easily retrievable. Note: assigning DOI numbers to items is optional, so not all resources have DOI numbers associated with them.
DOI Resolver System
The online DOI resolver system tells you information about the item, including where to get it. You might be prompted to buy the item, but never do that. Twin Cities Library can get the resource for you for free, either through one of our databases or through Interlibrary Loan.
Find more information about articles by entering the DOI number into the DOI Resolver System, available at http://dx.doi.org/
