Well, the buyer of the was Peter Harrington, of London. I've seen his books at the Boston Antiquarian Book Fair for the last few years - he's got great stuff and he's a high end dealer. Those interested now in owning Wilbury Crockett's former copy of The Colossus will have to shell out £37,500. The other items that sold have not yet surfaced in bookseller inventories so it it possible these went to private owners or other places.
Ian MacKay also wrote about this in the September 2007 issue of Fine Books Notes. See "A Colossal Colossus" here.
Crockett lived, at the time, at 9 Summit Road in Wellesley, according to Plath's address book, which is housed as part of the Sylvia Plath Collection at the Mortimer Rare Book Room, Smith College.
