Rysmiel is in Canada, but I don't know if they were found in person or not. abebooks.com sent me e-mail whenever one turned up, and though I missed a few by hours, it didn't take too long to collect the set. (And checking ABE & bookfinder.com now, there are copies of all of them listed as available.)

(Oh, and I've remembered someone else who bought them all, but I can't remember if she read them yet.)
