The graphic novels in the canon consist of sixteen published volumes in print. These are also available on the web, along with a complete and available seventeenth volume and an incomplete, ongoing eighteenth volume. Starting with the fourteenth volume, the story has now entered Act 2 and the volume numbers have started over at one. Volumes in Act 2 will be identified in the chronology by the act number, a dash, and then the volume number; for example, Act 2, Volume 1 (overall volume number 14) will be identified as 2-1. Eventually, the volumes in the first part, Act 1, will be renumbered to match. While "Act 1" and "Act 2" were originally used by the Foglios to refer to the two parts of Girl Genius, eventually they settled on The First Journey of Agatha Heterodyne and The Second Journey of Agatha Heterodyne as the official names for the two sections.
The chronology pages describe the comics to assist scholars in finding the page on which something occurred. For each comic, the chronology pages identify the characters that appear, actions taken, significant quotes, and other notes. Section titles are from the canon unless otherwise noted.
For a partial timeline of the events in the comic, see Internal Chronology.
