So... it turns out that someone in New York (a poet, in fact) received twenty-two of my precious missing books in the mail, all jumbled up with books of hers. It wasn't all of my books (Arcades Project? still missing), and in addition she wound up with three books belonging to an unknown third party. But my copy of This Sex Which Is Not One was in there, along with my complete Plato, my Myra Jehlen (what, I needed it just yesterday) and my Gubar-annotated A Room of One's Own.
Now I'm starting to have hope that my other books may return to me through the magic of the internet. (Yup, she googled me.)
So IF YOU HAVE MY BOOKS!: I really miss them. Send them?
