If the journal has no volume or issue numbers, you can instead put the month or season into the parentheses with the year. For example:
Fincher, L. H. (2013, Spring). Women’s rights at risk. Dissent. Retrieved from http://www.dissentmagazine.org/
Gibson, J. (2010, June). Veggie gardening with scissors and a spatula. Healthy Options, 48-49.
The month or season is not required in the in-text citation - only the year. For example:
An article from a journal supplement is referenced in a similar way to a regular journal article. There are at least two different types of supplements.
Murphy, L., & Heimick, C. G. (2012). The impact of osteoarthritis in the United States: A population- health perspective. American Journal of Nursing, 112(3, Suppl.), S13-S19. Retrieved from EBSCOhost database.
Rogers, J. W., Kinner, R. L., & Weis, V. (2013).The architecture of the gravitational lens. Astronomicity,16(Suppl. 2), 170-192.
If a magazine, newspaper or journal article is spread over a number of different pages, you give all page numbers and separate the numbers with a comma. For example:
Lewis, G. (2014, July 30). Job losses not isolated. Hamilton Press, pp. 1, 17.
