Citing Other Online Sources

 Advanced online publications

  • Before you submit your paper check to see if article is published.
  • If it has been published, cite the published version.
  • If no DOI is available use the journal URL Add "Advanced online publication" (without quotes) in place of volume number. Do not italicize.
  • Publishers may use different terminology for not yet published online resources (i.e. prepublished). But always use "Advanced online publication" in your citation.
