Digital comic book startup ComiXology is partnering with one of the biggest publishers of children’s books, Scholastic, the startup announced yesterday at San Diego Comic-Con.

The move represents ComiXology’s strategy to boost the number of publishing partners it has, thus allowing the company to continue selling more comic books, graphic novels, and other graphic fiction.

Earlier this year, the company opened up a new office in France and began offering foreign language titles to the service — some of which feature translated versions in English. And last year, ComiXology brought on its first big children’s book series with Diary of a Wimpy Kid being made available for purchase on ComiXology’s main app as well as its Comics4Kids iOS app.

Under terms of the deal, Scholastic will bring 19 graphic novels from its Graphix imprint to ComiXology’s digital store — adding to the over 40,000 pieces of content already available. ComiXology said future titles from the Graphix line will be released on a rolling basis.

The Graphix imprint wasn’t the only publishing announcement ComiXology made during Comic-Con. The startup, which just surpassed 180 million downloads of content since launching in 2007, also announced new publishing deals with Seven Seas Distributors and Udon Entertainment.
