Who's Who in the DC Universe

It was essentially an encyclopedia in comic book form, listing the characters, places, and technology in the DC Universe,[citation needed] with a loose leaf format devised by editor Michael Eury.

Another instance is a blank entry for Death, which has all the usual information headings crossed out and blue marker scrawl stating simply "Someday you'll meet her.

[citation needed] During the period from the late 1990s through the end of the 2000s, Who's Who was replaced with Secret Files and Origins, a series of one-shots devoted to particular characters or events in the DC Universe and which feature Who's Who-like profiles.

DK Publishing has also released a number of Ultimate Guides, as well as a book titled The DC Comics Encyclopedia, which serve a similar purpose.

The resulting New 52 comics are set in a greatly altered continuity, making a new edition of Who's Who unlikely in the short term because the histories of many characters are in a state of flux.

In 2022, The New Golden Age one-shot included 12 new Who's Who-style entries: Aquaman, Betsy Ross and Molly Pitcher, Cherry Bomb, Harlequin's Son, John Henry Jr., Ladybug, Legionnaire, Mister Miracle, Quiz Kid, Red Lantern, Salem the Witch Girl, and The Boom.

The DC Power 2024 one-shot included five new Who's Who-style entries: Black Manta, Mister Terrific (Michael Holt), The Signal, The Spectre (Crispus Allen), and Val-Zod.
