Russell Willis of Panel Nine has announced the iPad app Sequential will now carry a selection of titles from NBM Publishing, including Rick Geary's Madison Square Tragedy, Margreet de Heer's Science: A Discovery in Comics and Philosophy: A Discovery in Comics, and Renaud Dillies' Abelard, Betty Blue, and Bubbles and Gondola.

Sequential began as a U.K. app and launched in August in the United States. With a strong focus on indie and underground graphic novels, it started out with titles from U.K. publishers like Blank Slate, Myriad Editions and Knockabout but has since added titles from U.S. publishers Fantagraphics and Secret Acres. While comiXology goes wide, with apps for every device and comics for every taste, Sequential has taken a different path, with a curated catalog of graphic novels for a particular audience and a sleek interface for a single device, the iPad.

It must be working: Sequential's other announcement is that it will be a major sponsor of the MoCCA Arts Fest, together with the School of Visual Arts, Blue Sky Studios and Wacom. That sponsorship makes a lot of sense, as MoCCA features the sort of independent, literary comics and graphic novels that appeal to Sequential's audience — including NBM.
