The NYU Libraries guide to Citing Sources in APA STYLE has a section on citing “electronic” sources such as web sites, e-text sections and chapters, blogposts, podcasts etc. For example, here is a citation for a popular “point of care tool,” UptoDate:
Borody, T.J., Leis, S., Pang, G., & Wettstein, A.R. (2013). Fecal microbiota transplantation in the treatment of recurrent Clostridium difficile infection. In T.W. Post, P. Rutgeerts, & S. Grover (Eds.), UptoDate. Available from https://arch.library.nyu.edu/databases/proxy/NYU04665
Note, the use of “Available from” indicates that the URL will lead users to a download site rather than directly to the chapter. This is a distinction to be made, compared with “retrieved from” in this example:
Centers for Disease Control and Prevention. (2014, April 2). Centers for Disease Control and Prevention. Retrieved from http://www.cdc.gov/
The difference is that the first example is an NYU-licensed resource, so an outside user would be led to a site but not necessarily be authenticated to retrieve the full text. “Retrieved from” indicates that a direct download is likely, in this example a freely available web site, like the CDC (Centers for Disease Control and Prevention).
It’s iterative…which means “involving repetition” according to Webster’s. You might also visualize a literature search as the process of going “two steps forward, one step back.” As you gather information and ideas about the most relevant articles you find, your search terms can be revised and expanded (or narrowed). Here is how it looks:
Your professor may have asked you to submit a search “history.” Or, you may (and should) keep a paper trail of how and what terms you searched as you conduct a literature search.
The popular databases each have a way (idiosyncratic…) to “save” a search history.
