Advance online publications or online first publications generally refer to peer-reviewed work before it has gone to print. It may not have had a final edit or be formatted for final production.
When referencing, include the full date, not just the year. You should also include the phrase "Advance online publication" before the DOI. If there is no DOI and the article was retrieved electronically, give the URL of the journal home page.

If a journal article has a Digital Object Identifier (DOI) listed, you will always include this identifier in your reference. You will not have to include the URL of the journal's home page or of the database from which you retrieved the article if a DOI is available.
Can't see the DOI for the article you have found?
1. If you viewed a journal article in an online database and it does not have a DOI, you will need to do a Google search (using the journal title) to obtain the URL for the journal's home page. This information must be included in the reference. If the journal is no longer being published and it does not have a home page, then include the URL for the home page of the database from which you retrieved the article.
2. If you viewed a journal article in its print format, check if it has a DOI listed. If it does not, your reference to the article would end after you provide the page range of the article.
