Ah, looks like my question has already been addressed, but I missed it. http://blog.apastyle.org/apastyle/2014/11/how-to-cite-multiple-pages-from-the-same-website.html

What would be the guidelines for multiple articles from the same corporate author, without a date, such as two or more articles from the American Nurses Association like below (where the first entry is copied from your example, and the second is fictitious)? Multiple reference list entries: American Nurses Association. (n.d.). Know your disaster. Retrieved from http://nursingworld.org/MainMenuCategories/WorkplaceSafety/Healthy-Work-Environment/DPR/KnowYourDisaster American Nurses Association. (n.d.). A second really good article. Retrieved from http://nursingworld.org/link_to_the_really_good_article Would this become (American Nurses Association, n.d.a, para 2) and (American Nurses Association, n.d.b, para 15)? Or is there a more concise and effective way to properly cite both sources?
