A popular chemistry book's jump from a publishing titan to an OER pioneer could be pivotal for the open access movement. For the author, it's also a fitting tribute to his late son. John McMurry's textbook Organic Chemistry has helped millions of students across the globe pass the infamous gauntlet of its namesake class -- also known among stressed-out pre-med students as "orgo" -- since the book was first printed in 1984. For his bestseller's 10th edition, McMurry has decided to part ways with his longtime publisher, the industry giant Cengage, which has published the book since the beginning. He recently sold the rights to OpenStax, a nonprofit based at Rice University that is dedicated to developing open education resources (OER), learning and research materials created and licensed to be free for the user.
