I don't know anything about collected editions, but starting with Amazing Fantasy #15 I'm reading Amazing Spider-Man #1-100 (volume 1?).
After retiring 3 months ago I started collecting the original (volume 1?) Amazing Spider-Man # 51-100, mostly in the Marvel Tales reprints.
When I started looking it was very confusing with all of the various issue/series, etc.
Some years ago I got #1-50, all in Marvel Tales, plus Amazing Fantasy #15. My goal is to have 1-100.
As far as I've been able to determine, ASM #'s 57, 58, 71, and 72 were never reprinted as stand alone books.
So I have #57 which was reprinted in Marvel Tales #30 along with other stories, #58 in Ka-Zar #3, and an original 71.
That leaves only #72 - Rocked By The Shocker to complete the list. I haven't found that locally so will probably get it on Ebay.
Spider-Man has always been my favorite character and I still have about 30 original books from my youth. The last of those is #42 so as memory serves other things started to pull me away from Spidey around that time.
