Media Source, Inc. (MSI) recently announced a strategic repositioning across the company and its media group, which includes Library Journal (LJ), School Library Journal (SLJ), and The Horn Book. The change is part of MSI’s broader commitment to supporting librarians in their essential work—through trusted journalism, expertly curated books, and professional development that empowers them to lead, adapt, and advocate. 

Effective immediately, Hallie Rich, editor in chief of Library Journal, has been appointed editorial director of Library Journal and School Library Journal. In this expanded role, she will lead editorial strategy and content development across both publications. Hallie brings a deep understanding of the library landscape and a clear editorial vision, along with a strong track record of collaboration and innovation. The new structure is designed to better enable coordinated coverage across shared priorities—such as intellectual freedom, advocacy, leadership, and innovation.

Elissa Gershowitz, editor in chief of The Horn Book—a leading publication dedicated to children’s and young adult literature, known for its authoritative reviews and deep engagement with the field—will also now report directly to the CEO.

MSI Group publisher Rebecca T. Miller and SLJ's editor in chief and LJ and SLJ's partnerships & innovation director Kathy Ishizuka will both be departing the organization following long tenures of distinguished service. Their leadership and editorial contributions have been key to shaping MSI’s connection to the library community and in advancing the mission of its media brands. 

“As libraries continue to evolve, our role is to inform and empower them. Our goal is not only to help librarians meet the needs of their communities, but also to elevate the visibility, impact, and enduring importance of libraries in society,” said Robert Gogel, President & CEO of MSI. “We’re committed to investing in the platforms, content, and leadership that help librarians anticipate change, advocate for their communities, and inspire lifelong readers.” 

As is the case for many organizations in the field, MSI is navigating a rapidly evolving landscape. The organizational changes reflect a renewed emphasis on editorial excellence, cross-brand collaboration, and a commitment to addressing the long-term needs of the communities it serves. With LJ preparing to mark its 150th anniversary in 2026—and SLJ and The Horn Book having celebrated their 70th and 100th anniversaries respectively in 2024—this realignment honors their legacy while building momentum for the future.

Junior Library Guild (JLG), a separate division of MSI, also marked its 95th year in 2024. A nationally recognized curation service for libraries, JLG is known for selecting high-quality children’s and young adult books that help librarians build robust, engaging collections.
