Should a Norton Critical Edition be listed as a version or as a series in a works-cited-list entry?

Note: This post relates to content in the eighth edition of the MLA Handbook. For up-to-date guidance, see the ninth edition of the MLA Handbook.

As the following example from the MLA Handbook demonstrates, a Norton Critical Edition should be listed in the “Version” slot (107): 

Wollstonecraft, Mary. A Vindication of the Rights of Woman. Edited by Deidre Shauna Lynch, Norton Critical Edition, 3rd ed., W. W. Norton, 2009.

A critical edition is a particular version of a work and that knowledge may be useful to your reader.
