Over the last three years, the Open Textbook Library, now hosting upwards of 175 complete open textbook titles, has built these titles’ credibility and increased faculty exposure to open textbooks by incentivizing textbook reviews by faculty from institutions across the country. Libraries have been at the core of our outreach and are our most integral partners in reaching faculty and building capacity on campuses for open textbooks. At the invitation of our partner libraries, we’ve visited dozens of schools to seed and support their open education programs. As a result, our partner institutions’ data shows that over 40% of their faculty attendees to our workshops adopt an open textbook. This small pilot group of faculty has saved students over $410,000 in textbook costs in less than three years. This presentation will introduce attendees to the Open Textbook Network - a consortium of institutions working to help faculty overcome barriers to adoption of open textbooks, increase institutional capacity to support faculty adoption and use of open textbooks, and collaboratively develop new understandings and best practices of open textbook adoption and use. Attendees will learn more about what’s to come for the Open Textbook Library, our partners, our data, and why open textbooks are a sustainable avenue towards initiating and sustaining open education programming.
