[From DC Comics: Collecting the stories that first introduced the world to Planetary, this graphic novel features the adventures of Elijah Wood, a hundred year old man, Jakita Wagner, an extremely powerful and bored woman, and The Drummer, a man with the ability to communicate with machines. Infatuated with tracking down evidence of super-human activity, these mystery archaeologists of the late 20th Century uncover unknown paranormal secrets and histories, such as a World War II supercomputer that can access other universes, a ghostly spirit of vengeance, and a lost island of dying monsters.]
2 The Fourth Man (7-12). [From DC Comics: This second PLANETARY collection focuses on the team's mysterious benefactor, the "Fourth Man." After paying their final respects to a British occultist with ties to their group, Elijah Snow, Jakita Wagner, and The Drummer continue their super-human archeological studies as they visit a hidden government compound full of radioactive human guinea pigs, discover a fictional construct that has been made real and learn of a malevolent group known simply as "The Four." As these investigations take place, Elijah begins to learn some truths about both the Fourth Man's identity as well as his own hidden past. Featuring an introduction by Buffy The Vampire Slayer creator, Joss Whedon!]
The Planetary Reader (13-15). [After a two-year hiatus, the series is about to resume, and the Reader was published to get the entire series back in print (including the two trades).]

This stunning volume collects PLANETARY #13-18, featuring the continuing adventures of Elijah Snow, Jakita Wagner and the Drummer — the Archaelogists of the Unknown — as they piece together the mysteries of the world and begin a direct campaign against the four people hoarding Earth's unnatural secrets for themselves!

In this volume, Snow initiates the second part of his comeback plan to stop The Four, makes a startling revelation about his past, and uncovers information on the world's first moon shot...in 1851! As more and more secrets crumble, more and more new mysteries rise to take their place!]

One-Shot Team-Up Books

Topped with a dazzling cover by Jimenez, RULING THE WORLD finds the more-than-top-secret Planetary team covertly investigating the Authority, the pantheon-like team that considers the world its personal protectorate. But while Planetary investigates the Authority, the Authority is looking into something that leads directly to one of Planetary's most critical cases. Someone from the Authority's past is powering up the strange computer hidden deep in the Adirondacks that generates the weird map of the multiverse called the Snowflake...and something is coming through it.]

TERRA OCCULTA introduces a world very much like the one Planetary operates in—yet completely different. It is an Elseworld ruled by the Four—strange and powerful people who compile technology, dark secrets and hidden information, keeping it for their own sinister benefit. But the members of Planetary have formed their secret league to uncover all the dirty business of the Four—all the secret history they’ve kept hidden from the world in the last hundred years. The world is a strange place, and the trio that is Planetary is determined to keep it that way. But if Kent, Wayne and Prince are Planetary, then who are the Four? Find out in the crossover and Elseworlds event of the summer!]
