Meet Our Divisions

When we talk about GL group, we often talk about it as a whole.  However, we know that it can be confusing, since GL group is the parent company for all four of divisions and each division offers customers and vendors different services and products.


GL group provides shared services to each of its three divisions: Booksource, Turtleback Books, and Jaffe Book Solutions. These shared services include human resources, accounting, IT services, and facilities management. Basically, we help all of our divisions with a lot of the administrative tasks important to keeping a company functioning well. Each of our divisions manages its own sales, marketing, and operations.


Each GL group division is committed to providing literature, educational materials, and creative solutions that bring learning and imagination to the world and I’m proud of all of our employees’ hard work and dedication. You can read more about each of our divisions below!
