Superman was an ongoing comic book series featuring the DC Comics superhero of the same name. The second volume of the previous ongoing Superman title, the series was published from cover dates January 1987 to April 2006, and ran for 228 issues (226 monthly issues and two issues published outside the concurrent numbering). This series was launched after John Byrne revamped the Superman character in 1986 in The Man of Steel limited series, introducing the post-Crisis on Infinite Earths version of the Superman character.
After that limited series, Action Comics returned to publication and Superman vol. 2, #1 was published. The original Superman series (volume 1) became The Adventures of Superman starting with issue #424. Superman vol. 2 continued publishing until April 2006 at which point DC restored The Adventures of Superman to its original title and canceled the second Superman series.
