Dragonriders of Pern is a science fiction series initiated by Anne McCaffrey with the Hugo Award-winning novella Weyr Search in 1967. The stories feature human history on the planet Pern, which might be called human-draconian society for its lifelong inter-species relationships between humans and dragons. Anne McCaffrey wrote all the Pern stories until 2003; as of 2012, eight books by her son Todd McCaffrey or by Anne and Todd have continued the series. In all, there are 23 novels, two collections of short fiction, and a few uncollected works. That includes one book by Anne and Todd published in July 2012, several months after her death.
This complete list of Pern stories follows Pern historical order, which is very different from the order of composition or the order of publication. The sequence is also disputable at some points, because many of the works overlap in time or feature travel between times; limited annotations are provided here.
The point of reference for Pern chronology is "Landing", when transport ships arrived and human settlement began. Years, or "Turns" around Pern's sun, are counted After Landing or "AL".
The planet Rukbat 3 was surveyed about 200 years before settlement ("Landing").
These stories are set before and during the First Pass, from just before settlers landed on Pern until about fifty years afterward (0 to 50 AL).
Just after the First Pass, 58 years after landing.
Just before and during the Second Pass, about 250 years after landing.
Just before and during the Third Pass, about 500 years after landing.
Late in the Sixth Pass, about 1550 years after landing.
Just before and during the Ninth Pass, about 2500 years after landing.
One short story cannot be dated even approximately. Some readers have inferred that it takes place during the Second or Third Pass.
