Finding DOIs

If a DOI (Digital Object Identifier) exists for a publication, the APA style manual requires that it be included at the end of the citation in the reference list. Sometimes DOIs are listed in the article databases, but not always. To doublecheck whether or not a DOI exists, use this search feature at crossref.org.
