Yeshiva University Libraries have set ambitious goals for 2023-2025, strategically incorporating open educational resources (OER) into their initiatives. OER includes a diverse range of freely accessible teaching, learning and research materials, including textbooks, articles, videos, software and more, all made available under an open license. We also encourage using materials that are available via Yeshiva University Libraries. The move to OER adoption and leveraging library-licensed materials as textbook alternatives aligns with the university's commitment to supporting student success by addressing the escalating costs of textbooks and promoting equitable access to essential course materials.
