>>107641603Amazing Spider-Man:
Essentials go all the way to ASM #248. The Roger Stern finale (#249-251) are only available in the Spider-Man Roger Stern omnibus. So there is a massive "gap" there, if you are using the Essentials as a starting point.
The Alien Costume Saga collects #252-258. From there, I would recommend Epic Collection Ghosts of the Past, which collects #259-271.
ASM #272-288 are uncollected save for #287 as a bonus story in the Micheline/Larsen omnibus.
#289-359, '86-'91 Annuals, Spider-Man/Wolverine, the full Cosmic Spidey and Kraven's Last Hunt, and 1990/1991 Spidey Annual X-Overs, the Parallel Lives, Kraven's Last Hunt sequel, Lady Zemo GNs, and the Hobgoblin/Rose epilogue Web of Spider-Man issues are in five Epic TPBS (Kraven's Last Hunt, Venom, Assassin's Nation, Cosmic Spidey, Return of the Sinister Six, and Round Robin). Be warned though, the entire Inferno X-Over with Hobgoblin is incomplete as Assassin's Nation only has the ASM installments.
Alternatively, you can get the two Micheline omnibuses. Micheline/McFarlane collects #296-330 and 330-350 respectively. Warning: these omnibuses omit the annuals, all of the X-Overs for Cosmic Spidey and Inferno, and the Graphic Novels and while the McFarlane volume omits his adjectiveless Spidey run (which has it's own omnibus), the Larsen omnibus collects all seven of his adjectiveless spidey run plus several fill-in issues and a three part Spidey-Wolverine team-up, where they rescue the DC Captain Marvel, who spends the entire arc bound and gagged and hooded like a gimp.
