A large independent publisher based out of Illinois, they also have offices in Connecticut and New York. Source books was started in 1987 by Dominique Raccah. They also have several imprints, all founded within the last decade.
They started out publishing business books, but then expanded to gift books, nonfiction, and in the past five years in particular, fiction books.
They’ve published a number of New York Times Bestsellers recently including Radium Girls by Kate Moore, Sold on a Monday by Kristina McMorris, and The Only Woman in the Room by Marie Benedict.
They now publish fiction and nonfiction in a large variety of genres, including romance, literary fiction, young adult and children’s books. A good way to get a feel for what they publish is to browse their catalogue here.
They list all their imprints here. It is clearly mentioned if an imprint is closed or open directly under the listing. At the time of publication of this review, only nonfiction and romance are open to direct submissions. But that changes regularly, although nonfiction and romance are generally open for submissions, with the other imprints having shorter submission windows.
