Eliezer: If you have a bit of time on your hands (unlikely), you could probably write a short script that would: search all your quote files for urls check the pages they refer to for the corresponding quotes         if the page doesn't have the quote         go to the archive and repeat the same process for strategically selected pages there         (maybe binary search, to find the latest archived version) and finally replace the old defunct url with the archived one.

It would be a great time-saver, especially if you have lots more quotes up your sleeve :)
