When citing journal articles in APA style, it is advisable to include the Digital Object Identifier (DOI), even when using the print source. This alphanumeric code provides a stable, long-lasting link to the article. It is NOT the same as an ISBN or accession number.
You can find the DOI in the following places:
Article description page in OneSearch and other library databases
Article PDF
Search article title in http://crossref.org/
If there is no DOI for an article, use the URL for the journal homepage or the URL where you found the article. It's also best to check the APA Style Guide for more details
