As a publisher, Houghton Mifflin shapes ideas, information, and instructional methods into various media that satisfy the lifelong need of people to learn, gain proficiency, and be entertained. Houghton Mifflin seeks out, selects, and generates worthwhile concepts and then enhances their value and accessibility through creative development, design, production, marketing, sales, and distribution. While Houghton Mifflin’s works have been published principally in printed form, programs or works are also published in other formats, including computer software, laser discs, CD-ROM, and Internet-based platforms.
