How do I list a reference for an article that does not have a DOI?
If no DOI is listed, include the URL of the journal home page as the source of the article.
Where do I find the URL of the publisher?
There is no standard format for the listing of the publisher URL. The journal homepage URL can often be found by clicking on the hyperlinked title of the publication in Source field of the article citation.
This will take you to a page with information about the publication, which often includes a URL for the publisher.
Method for citing:
O'Shea, L. (2002). An economic approach to reducing water pollution: Point and diffuse sources. Science of the Total Environment, 282-283, 49. Retrieved from http://www.elsevier.com/
If not listed, the publisher URL can be found by searching the title of the publication on Google.
