Open Educational Resources (OER) have traditionally been defined as digital materials that may be used for teaching, learning, and research and made available free through open licenses. More recently, there has been a movement to broaden this definition. Many experts now believe that a more precise definition of OER impinges on the range of views regarding fundamental questions associated with interpretations of the meaning of “freedom to learn.” Perspectives on OER edited by Rocco Paolucci explores the more recent academic research on opportunities and challenges presented by OER to educational institutions, with emphasis on how these relate to those who are in most need of these resources (particularly in developing countries). In addition to discussing examples of successful ways to access and share resources of open educational projects, it attempts to address what is meant by “open” and the number of ways leading institutions are becoming more open and innovative.
