The MLA Handbook gives examples of how original publication information can be provided as an optional element in a works-cited-list entry (53). But MLA style generally avoids annotating works-cited-list entries: if information is important for the reader to know, it belongs in your discussion or in a note.
For example, let’s say that you quote from the following version of Isaac Asimov’s I, Robot, a novel that was originally published as a series of short stories:
Asimov, Isaac. I, Robot. 1950. www.ttu.ee/public/m/mart-murdvee/Techno-Psy/Isaac_Asimov_-_I_Robot.pdf.
In an endnote, you might explain the original publication context for the novel, . . .
