This version of the JSA chronology preserves the original, or "post-Crisis" era, timeline and omits the changes wrought by Crisis on Infinite Earths (which eliminated Earth-Two heroes Superman, Batman, and Wonder Woman). It lists events from the Golden Age through Earth-Two continuities, and adds post-Infinite Crisis events that appeared to pick up from those.
Events do not include the post-Crisis series Young
All-Stars, or Infinity, Inc. after issue #24 (when character histories began to change).
Some details revealed in the post-Crisis tales in Secret
Origins are included here if they do not contradict any original
tale(s). The Secret Origins tales were largely written by
Roy Thomas, who knew these characters intimately. It is usually easy
to tell when Thomas intended for events to fit with original
continuity, and when he intended to change events for post-Crisis
continuity.
Post-Crisis tales of Earth-Two are included. There aren't many. They
include the Gentleman Ghost story from JSA #83-85 (2006) and
the introduction of Justice Society Infinity in Justice
Society Annual #1 (2008).

anomalies
Characters' first appearance IN PRINT is bolded.
These instances refer to the first appearance a character in post-Crisis
continuity. (For example, Brain Wave: first chronological appearance in All-Star
Squadron #19, and first appearance In print is All-Star Comics #15.)
When the placement of a tale within continuity is in
question, the tale is usually placed in the most recent possible
time.
Only the inheritors to a title display the level
of succession. Example: "Green Lantern II" (for
Hal Jordan), but just "Green Lantern" (no "I" for
Alan Scott).
Consideration for inclusion is based on an event's
relevancy to the JSA, its members, and their legacy. This includes
major JSA series and key issues from other DCU series.
