...now, I'm perfectly happy with even modern paperback editions of things. But there's something to be said -- just for instance -- about the wonder of being able to hold an edition of Trollope that was once handled, and signed, by the author himself.
(Actually, though, two of the three I would most want are the two cheapest ones. The other, which likely comes as no surprise to those who know me well, would be the autographed Collins.)
If I ever win the lottery...
