The term "Big Publisher" refers to a large publishing company that has the resources and infrastructure to produce, market and distribute books on a mass scale. These companies typically have long-standing relationships with authors, agents, bookstores, libraries, and other industry partners. They often work with well-known or established writers as well as taking chances on new talent. Big publishers may also own their own imprints, which are smaller publishing houses within the larger company that focus on specific genres or audiences. Overall, big publishers play a significant role in shaping the literary landscape and bringing books to readers around the world.
