With the release of Peter Jackson’s movie adaptations of J.R.R. Tolkien’s fantasy novel "The Lord of the Rings", Houghton Mifflin hired both James Morrow (on the strength of his published instructional materials) and Kathryn Morrow (given her extensive knowledge of Tolkien’s oeuvre) to write a book-length curriculum for middle-school and high-school teachers wishing to bring "The Hobbit" and "The Lord of the Rings" into their classrooms. The resulting resource, "Tolkien’s Middle Earth: Lesson Plans for Secondary School Educators" (Houghton Mifflin, 2006), was posted on the publisher’s website.
