Reprints Batman Confidential #26-28 (April – June 2009), The Brave & The Bold #164 & 171 (July 1980 & February 1981), and Batman #353 (November 1982).
Placed here as a most likely fit based on elements of the Batman Confidential story: the Riddler has been active for some time; Robin exists but is not working with Batman at this time (suggesting that this takes place after Dick Grayson leaves Gotham but before Jason Todd assumes the role).
Batman: Strange Apparitions
Aquaman: Death of the Prince
Mister Miracle by Steve Englehart and Steve Gerber
Reprints Miracle Miracle #19-25 (September 1977 – August-September 1978); The Brave and the Bold #112, 128 & 138 (April-May 1974, July 1976 & November 1977) & DC Comics Presents #12 (August 1979).
Placed here based on the original publication dates of the Miracle Miracle issues.

Placed here for the earliest appearance of Ra’s al Ghul.
Batman: Night Cries
Manhunter by Archie Goodwin and Walter Simonson
This is the Paul Kirk version of the character.
Batman: Through the Looking Glass
Original graphic novel (2011).
This is a difficult story to place, as Batman appears not to recognise several well-established villains (the Mad Hatter, Tweedle Dee and Tweedle Dum) during this story, which would seem to imply that this is their first appearance. On the other hand, Robin’s age argues for a later placement – and there are no other chronological cues in the book. I have chosen to assume that Batman’s addled state throughout much of this story accounts for his failure to recognise the villains and placed it here as a best fit.

Batman: Blink
Reprints Legends of the Dark Knight #156-158 & 164-167 (August 2002 – October 2002 & April 2003 – July 2003).
This book contains two stories, one occurring approximately midway through the year, the other in winter a few months later. Gordon is referred to as Lieutenant rather than Captain throughout (he was promoted to Captain near the end of Year One), but the working relationship between him and Batman argues for this later placement.
Batman: Snow
Set before The Long Halloween, about 18 months after Batman’s first appearance.
Batman: The Long Halloween
Begins in June of Year Two, and continues into Year Three.

Reprints Tarzan #207-235 (April 1972 – February/March 1975).

1938

The Last Days of Krypton
Original prose novel by Kevin J. Anderson (2008).
It’s not a graphic novel – and possibly not canonical – but it is very good. It’s placement here is based on the date of Superman’s first appearance, which has been mentioned more than once as the date of Krypton’s destruction.
DC Universe: Legacies
Reprints DC Universe Legacies #1-10 (July 2010 – April 2011).
The story begins in this year, and carries through until Infinite Crisis in Year 20.

Reprints Madame Xanadu #1-10 (August 2008 – June 2009).
This volume tells the story of Madame Xanadu from the fall of Camelot in 515 CE to her arrival in New York City in 1940, but is best read here.

The Golden Age portions of this volume (the stories from Star Spangled War Stories) take place during World War Two. Their placement here is an approximation.
Creature Commandos
Reprints Weird War Tales #93, 97, 100, 102, 105, 108-112, 114-119, 121 & 124 (November 1980; March 1981; June 1981; August 1981; November 1981; February 1982-June 1982; August 1982-January 1983; March 1983 & June 1983).
These stories take place across 1942-1944 and their internal continuity does not match that of the actual war. Their placement here is an approximation.
Blackhawk: Blood and Iron
Reprints Blackhawk #1-3 (March 1988 – May 1988); Secret Origins #45 (October 1989) & Action Comics Weekly #601-608, 615-622 & 628-635 (May 1988 – July 1988, August 1988 – October 1988 & November 1988 – January 1989).

1948

JSA: The Golden Age
Reprints The Golden Age #1-4 (Summer 1993 – Spring 1994).

The Silver Age portions of this volume (the stories from The Brave and the Bold) take place at around this time.

The Post-Crisis DCU 03 – Year One

Superman: Secret Origin
Reprints Superman: Secret Origin #1-6 (September 2009 – August 2010).
This version of Superman’s origin is incompatible with those presented in Superman: The Man of Steel and Superman: Birthright. Superman’s first public appearance kicks off the modern heroic age.
Superman: Kryptonite
Reprints Superman Confidential #1-5 & 11 (January 2007 – June 2007 & March 2008).
Stated to take place “about two months” after Superman’s public debut, tells the story of Superman’s first encounter with Kryptonite, which contradicts other stories.
Superman: The Man of Steel
Reprints The Man of Steel #1-6 (July 1986 – September 1986).
The later stories in this volume were originally intended to have occurred later on in Superman’s career, and only the stories up to meeting Lex Luthor actually occur this year, but this has often been ignored by later writers (and was not amazingly clear in the original).
Batman: Year One
Reprints Batman #404-407 (February 1987 – May 1987).
Batman is the next hero to appear after Superman. There is some overlap in time between the events of this book and those of Man of Steel. In addition, this book is also in continuity on Earth-31, the Dark Knight’s Earth.
Catwoman: Her Sister’s Keeper
Reprints Catwoman #1-4 (February 1989 – May 1989).
Parallels events in Batman: Year One.
Superman for All Seasons
Reprints Superman For All Seasons #1-4 (September 1998 – December 1998)
Must precede Birthright, as Luthor is unaware of Superman’s alien nature.
Batman and the Monster Men
Reprints Batman: The Monster Men #1-6 (January 2006 – June 2006).
Takes place during Batman: Year One.
Superman/Shazam!: First Thunder
Takes place during Batman’s first year, but before Wonder Woman, the Flash or Green Lantern’s debut.
Green Arrow: Year One
Must occur around this time, but placed here by fiat.
Superman: Birthright
Reprints Superman: Birthright #1-12 (September 2003 – September 2004).
Batman and the Mad Monk
Reprints Batman: The Mad Monk #1-6 (October 2006 – March 2007).
Takes place during Batman: Year One.
Green Arrow: The Wonder Year
Reprints Green Arrow: The Wonder Year #1-4 (February 1993 – May 1993) & Green Arrow #73-80 (April 1993 – November 1993).
Collected in a volume entitled Green Arrow, vol.9: Old Tricks – only the Wonder Year miniseries takes place at this time.
Batman: Lovers and Madmen
Reprints Batman Confidential #7-12 (September 2007 – February 2008). Depicts Batman’s first clash with the Joker, overlapping slightly with the later events in Batman: Year One.
This volume and Batman: The Man Who Laughs depict alternate origins of the Joker, and thus cannot both be in continuity.
Batman: The Man Who Laughs
Chronicles Batman’s first clash with the Joker, following on directly from Batman: Year One.
This volume and Batman: Lovers and Madmen depict alternate origins of the Joker, and thus cannot both be in continuity.
Batman: Prey
Chronicles Batman’s first clash with Hugo Strange. Both this book and The Man Who Laughs give different origins for the Bat-Signal which cannot be reconciled.
Batman: Gothic
Must occur early in Batman’s career, before he is joined by Robin but after the Bat-signal is introduced. The text states that it is 20 years since the murder of Bruce’s parents (as opposed to the 18 years figure of Batman: Year One), but this can reasonably be considered an approximation rather than a literal figure.
Batman: Dead to Rights
Reprints Batman Confidential #22-25 and 29-30 (December 2008 – March 2009; July 2009 – August 2009). This story depicts Batman’s second clash with the Joker.
Batman/Superman/Wonder Woman: Trinity
must occur before Aquaman’s public debut.
Green Lantern: Emerald Dawn
Green Lantern: Secret Origin
There are minor contradictions between these two versions of Green Lantern’s origin, but nothing so major as to conclusively rule out either. They are best read in this order.
Green Lantern: Emerald Dawn II
Flash vs. The Rogues
Reprints a bunch of early clashes between the Flash and various supervillains., and occurs more or less in parallel with the Green Lantern volume.
Aquaman: Time and Tide
Reprints Aquaman: Time and Tide #1-4 (December 1993 – March 1994).
Must occur after the Trickster’s first appearance in The Flash vs. The Rogues.
