X-Men: The Lost Years (Amazing Adventures #11-17 (transformation of The Beast), Incredible Hulk #150, 161, 172, & 180-181 (debut of Wolverine), Amazing Spider-Man #92, Marvel Team-Up #4, 23, & 38, Avengers #110-111, Captain America #172-175, Defenders #15-16, and Giant-Size Fantastic Four #4 + Fantastic Four (1961) #102-104 and Amazing Adventures Vol. 2 (1970) #9-10 + 22-issue series of “X-Men: The Hidden Years”)
and the 2 omnibus Krisis suggested:
X-Men: Crossroads Omnibus (UXM #199-209 + Ann 9-10, NM 35-45 + Ann 2 & Special Edition, X-Factor #1-8 + Ann 1, Marvel Fanfare #33, Alpha Flight #33-34, X-Men: Heroes for Hope, Firestar #1-4, Fantastic Four #286, Avengers #263)
X-Men: Before the Fall Omnibus (Collects Uncanny X-Men #215-219 & Annual 11, X-Factor #12-17 & Annual 2, and New Mutants #47-54 & Ann 3, Mephisto vs. X-Factor, Mephisto vs X-Men, Spiderman and Wolverine #1, Marvel Fanfare #38 (Rogue/Dazzler backup), X-Men vs Fantastic Four #1-4, X-Men vs Avengers #1-4, Fallen Angels #1-8, and Marvel Super-Heroes #1 (Magik story))
it would be the best way to include the mini series and crossovers and moove on to other X-factor (90's by Peter David, J. M. DeMatteis and Todd DeZago) and New Mutants Omnibus (it would continue from a 1st NM Omnibus)
