Finally, in 1976 he and his co-author, Robert P. Hostetler, obtained a contract from D. C. Heath and Company. The first edition of their calculus book was published in December, 1978. In 1995, Hostetler left the authorship team and was replaced by Bruce A. Edwards of the University of Florida. Calculus by Larson and Edwards is now in its eleventh edition. It is used worldwide and has been translated in several languages. During the academic year of 1983–84, Larson served as the acting division head for the Division of Science at Penn State Erie. In 1998 Larson was given the Distinguished Alumnus Award from Lewis and Clark College, Portland, Oregon. Books Counting different editions, Larson has written over 400 titles. They are used by several million students each year in the United States, as well as by students in other countries. Larson's books have received many awards – for pedagogy, innovation, and design. One of these awards was for developing the first completely interactive calculus textbook online. The work on this text was spearheaded by Larson's son, Timothy Larson. The online text, titled Interactive Calculus was posted in 1995. Another award was for innovation in page design. Beginning in 1990, Larson has written all of his mathematics texts to design, so that concepts and examples never break from page to page. The eighth edition of Calculus won the 2005 Benny Award for the best cover in all categories of printing. The middle school series, Big Ideas Math, won the TAA Textbook Excellence Award ("Texty") in 2010 for excellence in secondary mathematics textbook publishing. Larson's textbooks have won awards from the Textbook Authors' Association (TAA) multiple times, including the McGuffey Longevity Award, the TAA Textbook Excellence Award, and the Most Promising New Textbook Excellence Award. Up until 1995, most of Larson's books were published by D. C. Heath, which was owned by Raytheon. In 1995, Raytheon sold D. C. Heath to Houghton Miffin. By 1999, Larson's titles had become a major component of Houghton Mifflin's publications. In that year, he was listed in the company's annual report as one of Houghton Mifflin's major authors. In 2008, the College Division of Houghton Mifflin was sold to Cengage Learning. Larson's
