Freeing the Textbook: Educational Resources in U.S. Higher EducationThe study results show that there is little question that OER awareness and use will continue to grow. Growth has been slow but steady for the past four years, held back by lack of awareness of OER and a perceived lack of offerings. However, OER could provide an answer to faculty cost concerns, while also supporting the 'revise' and 'remix' approach to textbook content that they are already using. This, combined with a growing acceptance of digital media and the impact of potential institutional initiatives around the cost of textbooks, could accelerate future expansion of OER awareness and use.
