DOI - Digital Object Identifier
DOIs are a series of numbers/letters allocated to journal articles. Not all Journal Articles will have a DOI but most do. Whenever you load a source in our databases, look for a DOI to help you cite that source in Citemaker. Also look for a DOI on any Journal Article you may find online. This is an example of a DOI: 10.1111/hex.12487. This tutorial will step you through how to record a source in Citemaker using a DOI.
