Roger Rosen has acquired Enslow Publishing, which does nonfiction titles for children and young adults in subjects that range from biography to science and technology.

Enslow will remain a standalone company, although under new leadership. The company, which sells primarily to the school and library markets, has been run by Mark and Brian Enslow, sons of the company founder. Rosen said he expects to name a new director soon.

New leadership is not the only change Rosen plans for Enslow. “I will be introducing a broad range of digital and other initiatives,” Rosen said, citing such forthcoming products as e-books, interactive titles and databases. Rosen also plans to expand Enslow’s direct-to-parent business.

Rosen, who is president of Rosen Publishing, bought the company himself as a boutique publisher and Enslow will not become part of the larger publishing operation.
