Notes:
As part of the Age of Apocalypse, Uncanny X-Men becomes Astonishing X-Men for the next four issues. The series returns to normal in July 1995 with issue #322, but you may need to read X-Men: Prime to get completely caught up.
For four months, Marvel tested a higher grade glossy paper on most of their X-titles (Deluxe) and offered the same issue printed on standard newsprint at a lower price point two weeks later.
