Sourcebooks has acquired duopress, a 15-year-old independent publisher headquartered in Baltimore. The sale was finalized on Tuesday, and Sourcebooks will become the vendor of record on May 1, with duopress titles transitioning from distribution by Workman Publishing to Sourcebooks. duopress will become an imprint of Sourcebooks Kids, with 15 frontlist titles scheduled for release each year under that imprint. Company founder Mauricio Velázquez de León, who will remain in Baltimore, is joining Sourcebooks on April 1 as duopress editorial director. He will report to Catherine Onder, Sourcebooks v-p, publisher of children’s books.

Under the deal, Sourcebooks has acquired more than 100 titles and products, including children’s high contrast titles; and the TummyTime, Babies Around the World, and Terra Babies at Home board book series. While duopress is best known for its list of board books, regional board books, counting books, and doodle books, it also publishes nonfiction middle grade titles, flashcards, sticker books, games, and puzzles, as well as parenting and adult gift books. The financial terms of the sale were not disclosed.

“I’ve always admired the energy and publishing IQ of Dominique Raccah and her extraordinary team at Sourcebooks, and we are incredibly excited to start this new chapter for duopress,” Velázquez de León said in a release. “I’m confident that Sourcebooks will be a great home for our backlist and the perfect launchpad to many more creative books and gifts for years to come.”

In an interview, Velázquez de León said there were no layoffs among his "small staff," and that they are moving with him to Sourcebooks.
