Abstract: The free, on-line, open-source, introductory astronomy textbook by Fraknoi, Morrison, and Wolff, which is part of the non-profit OpenStax project, now has over 1,100 adopters and is being used by some 160,000 students per year. So far it has saved students more than 39 million dollars in astronomy textbook costs. The book's Open Education Resources Hub has over 35 free ancillary materials, including new resource guides to “Black Lives in Astronomy.” “Short Videos Organized by Astronomy Topic,” “Plays and Films about Astronomers,” a “Guide to Astrophotography with your Cell Phone,” and “An Updated List of Astronomy Simulations.” There is a new “Expert TA: Astronomy” Learning Management System that includes a computerized bank of automatically graded multiple-choice questions, true-false questions for review, calculation problems, and graphical questions. More than 75 astronomers have contributed to this community project. The book URL is (and you can get to the OER Hub from the Instructor Resources page.)
