PHILADELPHIA — A comic book publisher says it has acquired another firm in a move that creates one of the largest stables of characters and titles of any independent publisher.

BOOM! Studios said Monday that it acquired Archaia Entertainment, whose titles include "Mouse Guard" and "Fraggle Rock." BOOM! will continue publishing its comics and graphic novels under Archaia's own imprint as it expands its roster of titles and graphic novels.

BOOM! did not reveal the price paid for Archaia's intellectual property but says the deal gives a push to Archaia's titles because of BOOM!'s extensive marketing operations and outreach.

Ross Richie, who founded BOOM! and is its CEO, says plans are also in the works to reissue some Archaia works.
