You're ready...! Almost... part 3

This would not be complete if I forgot mentioning Spider-Man. He's a very popular super hero and is probably now more than ever since it also became a Hollywood blockbuster. Actually, thanks to this rise in popularity, Marvel has been re-printing old issues so if you're interested in a specific super-hero, you now can buy trade paperbacks collecting them (usually titled Essential [insert hero's name]... Be careful though, it's usually printed on low quality paper and WILL be in black and white.
As I have not read ALL of spider-man books, i will, once again, try to list some of the ones that I think are really worth reading:

Spider-Man: Death of Captain Stacy by Stan Lee
A must read in which Captain Stacy (spider-man's mentor) gets assassinated.

Spider-Man: Death of Gwen Stacy by Gerry Conway and Gil Kane
Spider-Man's first love goes down... Just please take note that another trade paperback titled Spider-Man: Death of the Stacys is out and collects both those stories... Just keep in mind it does not include all the issues (missing Amazing Spider-Man Vol. 1 #96-98) so you may want to buy them separately.

Spider-Man: Clone Genesis by Gerry Conway and Len Wein
Contains the original stories of the Spider-Man Clone saga which makes a big part of Spider-Man stories. Anyone who is not familiar with this era should pick up this book.

Spider-Man: Birth of Venom by too many to write it down here...
As the title says, this book is about the birth of Venom and will give you the full background story of the Alien Costume that eventually became Venom.

Spider-Man: Kraven's Last Hunt by J.M. DeMatteis and Mike Zeck
Kraven was, in my opinion, the best Spider-Man's foe ever. This is by far my favorite Spider-Man story and Mike Zeck's art conveys that dark atmosphere perfectly. It is not their first encounter as Spider-Man has defeated Kraven in the past, but even you're new to Spider-Man, I believe this is THE book you have to read and won't regret it.

There you go... 5 books really worth mentioning. I haven't listed any dealing with Carnage... And some may not agree with me but I think those were just boring.
