A textbook writer develops textbooks to educate students according to the specifications of their publisher. As a textbook writer, your typical duties are to write a book outline to gain approval from the publisher, develop the content for the book, and add a lesson or review questions at the end of the chapters, depending on the subject and type of textbook. Other responsibilities may include creating textbooks for a school or academic institution, updating existing books for schools and publishers to reprint, developing learning guides for students to use along with the primary manual, adapting books to other formats, such as ebooks, and ensuring the accuracy of information.
