The article was republished in Methods of Rhetorical Criticism: A Twentieth-Century Perspective, ed. Bernard L. Brock, Robert L. Scott and James W. Chesebro, Third Edition, Revised, 1990 (Detroit: Wayne State University Press), pp. 223-233. I have included a link to this version as well as to the original.
There is some overlap between this article and the earlier "The Changing-Unchanging Heroines and Heroes of Harlequin Romances, 1950-1979" (from 1983): two out of the three novels chosen to represent the 1950s-1970s are the same. However, Hubbard then goes on to examine romances from the early 1980s (at this point she introduces some non-Harlequins) and discovers considerable differences between them and the novels from earlier decades with respect to gender roles/gendered behaviour.
Under the title "Magic and Transformation: Relationships in Popular Romance Novels, 1950 to the 1980s" the 1985 article was reprinted again, in 1992, this time in Popular Culture: An Introductory Text, ed. Jack Nachbar & Kevin Lause (Bowling Green, OH: Bowling Green State University Popular Press), pp. 476-488. It is stated there that "A slightly different version of this essay appeared in Communication Quarterly 33 (Spring 1985)." Here is a link to that edition. The version titled "Magic and Transformation" omits the section which in "Relationship Styles" is titled "The Critical Method" as well as omitting most of the two paragraphs leading up to it and there are some other cuts and some minor alterations.
