Houghton Mifflin Harcourt is an American publishing company formed from the merger of two storied houses, Houghton Mifflin and Harcourt, both with deep roots in literary, educational, and reference publishing stretching back well over a century.
The combined company became a major force in educational publishing, producing textbooks, curricula, and learning programs used in schools across the United States, alongside a trade list of literature and general-interest books.
In reference it carried forward the American Heritage Dictionary line, one of the leading American dictionaries, known for its clear definitions and its respected usage guidance.
The company has navigated the shift from print to digital learning, developing educational technology and digital programs while maintaining its traditional publishing strengths.
Its educational and reference titles remain widely used in classrooms and homes across the country, reflecting the long legacy of both founding houses.
