(Note: Most GSU social science faculty will accept this format if you are citing the PDF format of an article retrieved electronically from a database, since the PDF format is exactly the same as the print. Most scholarly journals are continuously paginated throughout a volume. The issue number is unnecessary to include unless the issues are paginated separately.)
Goldstein, G., Luther, J. F., Jacoby, A. M., Haas, G. L., & Gordon, A. J. A preliminary classification system for homeless veterans with mental illness. Psychological Services, 5, 36-48. doi:10.1037/1541-1522.214.171.124
APA is now recommending that the DOI be included if available because this number is unique and permanent and will allow for accessing the citation through the Internet without knowing the specific database from which it was retrieved.
