The day-to-day operations of BISG are run by a two-person team: Executive Director Brian O'Leary and Operations Manager Brooke Horn. We also rely on the volunteers of our Committees and our Board of Directors to help us continue to provide the services needed to ensure BISG supports our members.

Brian O’Leary

Executive Director

Tel: 646-336-7141

As Executive Director, Brian helps ensure that BISG disseminates information, creates and implements standards, and conducts research to benefit the book publishing supply chain.

Before being named to this role in 2016, he was principal of Magellan Media Consulting, which helped publishers improve how they create, manage, and distribute content. In that role, Brian wrote extensively about issues affecting the publishing industry. He also co-edited Book: A Futurist's Manifesto (O'Reilly Media, 2012) with Hugh McGuire.

Brian served as SVP with Hammond Inc. and oversaw production and distribution operations at several Time Inc. magazines. He joined Time Inc. after earning an MBA from Harvard Business School and also holds an AB in chemistry from Harvard College.

Brian tries to dedicate his spare time to gardening and building model rockets and model railroads. His favorite author is Thomas Wolfe (not Tom Wolfe—an entirely different kettle of fish).

Brooke Horn

Operations Manager

Tel: 646-336-7141 

As Operations Manager, Brooke supports the work of BISG’s five committees, plans and markets webinars and events, and helps ensure that BISG continues to benefit the entire publishing supply chain.

A content maven, she has over eight years of experience in the book industry spanning roles in editing, acquisitions, project management, marketing, metadata, and bookselling. Her former roles include Junior Education Project Manager at Guilford Press, where she coordinated the development, planning, and marketing of education catalogs, and Acquisitions Editor for Pediment Publishing, where she acquired content for history books and managed their development through publication. 

She holds a BA in English from the University of Florida and a MS in book publishing from Portland State University. In addition to serving as Operations Manager for BISG, Brooke is copyeditor of The Journal of San Diego History and book matchmaker at Taylor & Co. Books in Brooklyn.

In her free time, Brooke enjoys taking photographs, caring for her collection of houseplants, and exploring the many parks, museums, and purveyors of caffeinated beverages New York City has to offer. She’ll happily chat with you about her latest read, but please don’t ask her who her favorite author is.
