I have been informed that Creeley was not on the Gloucester shelf, but that the Black Mountain and the Gloucester share a shelf. I should have noticed Duncan there. Williams was just there to make more room in general poetry.
Found the Christie's catalog for the sale of the John Quinn Draft Manuscript of the 'Circe' episode in Ulysses. That should go with the Joyce. I don't think I'll keep many other auction catalogs.
I am not having fun with this anymore, but every room is covered in books and I can't stop now. There just isn't enough space on the shelves.
