Another more closely argued essay, Robin Gail Schultze's ' "The
Frigate Pelican" 's Progress: Marianne Moore's Multiple Versions and Modernist Practice', also addresses issues of literary history, but by a specific focus on textual concerns, and how Moore's habit of writing different versions of the same poem at different moments in history, while reflecting the sensitivity of response to contingent reality, also mitigates against full recognition of the scope of her achievement, since subsequent editors tend not to publish full variorum collections.
