I downloaded a torrent not too long ago that has all of the clone saga issues, but the guy who upoaded them put up a list of 224 issues. It's massive, but there are about 35 issues in this group that really have nothing to do with the clone saga at all, but they almost act as a catalyst in some respects. There is a steady build up of events that took place in the spidey books from the 70's-90's like the goblin legacy, doctor octopus unmasking spider-man, the introduction of the hobgoblin, the introduction of venom, the death of Kraven, the return of Peter's parents, the death of lance bannon, ned leeds is revealed as the hobgoblin, and so on and so forth.
