Open educational resources (OER) are educational materials with an open license so that they can be freely copied, modified, and reused. While the rising cost of textbooks is a concern in higher education, over 50% of the surveyed educators stated that they are unaware of the OER and how they could replace the traditional textbooks. In addition, not many instructors understand the Creative Commons licenses under which OER can be used. In this work, we consider the types of OER and outline the sources of OER for business courses. We describe our experience of using such resources for innovative business courses and discuss the choices we made and the lessons learned. Finally, we share the results of surveys about OER we conducted with students and reflect on them.
