Released in 2004, this hardcover book had Who’s Who type entries for most DC characters and events. Writing credits have been given to Scott Beatty, Robert Greenburger, Phil Jimenez, and Daniel Wallace. Captain Atom appeared several times (the Modern Age Captain Atom primarily, but also the Bronze Age Cap and Monarch). Hundreds of artists are credited but where in the book their work appears is not specified. Most of the artwork, if not all of it, is recycled from previously published works.
The Modern Age Captain Atom drawing is from JLA-Z #1 by Dan Jurgens & Al Vey. The JLI featuring the Cap is from JLA-Z #2 by Kevin Maguire & Josef Rubinstein. The image of the Bronze Age Cap and others attacking the Anti-Monitor is from the cover of Crisis on Infinite Earths #12 by George Pérez & Jerry Ordway. The Extreme Justice drawing is from the cover of Extreme Justice #0 by Marc Campos & Ken Branch. I could not track down the artists behind the drawings of Monarch and the rendition of Zero Hour.
An updated and expanded version of the encyclopedia was released in 2008.
