Do I need to create a separate works-cited-list entry for every work I use from the same database?

Yes, each work you cite from the same database requires its own works-cited-list entry, as shown in the example below:

Some scholarship on genre addresses the rhetoric of housework (see, e.g., White-Farnham; Courtney).

Courtney, Jennifer. “Real Men Do Housework: Ethos and Masculinity in Contemporary Domestic Advice.” Rhetoric Review, vol. 28, no. 1, 2009, pp. 66–81. JSTOR,

White-Farnham, Jamie. “‘Revising the Menu to Fit the Budget’: Grocery Lists and Other Rhetorical Heirlooms.” College English, vol. 76, no. 3, Jan. 2014, pp. 208–26. JSTOR,

This practice follows the guidelines for citing more than one page from the same Web site.
