Electronic book and magazine distributor LibreDigital has raised $15 million in a second round of funding. New investor Triangle Peak Partners led the round, with participation from previous backer Adams Capital Management. The company previously raised funding from investors like HarperCollins Publishers (which uses LibreDigital for distribution) and The New York Times.

Austin, Texas-based LibreDigital will use the new money to continue building out its cross-device e-book platform, and for marketing—to help sign on more publishing partners. It currently distributes over 175 newspapers and magazines and boasts partnerships with publishers including Hachette, Simon & Schuster and Wiley. The company most recently inked a deal to power content for Plastic Logic’s upcoming bigger, thinner Kindle-challenger.
