Open Textbook Network / Open Education Resources: What is Open and Why is it Important?

What are Open Education Resources?

Open Education Resources, commonly referred to as OER, are defined by UNESCO as:

"any type of educational materials that are in the public domain or introduced with an open license. The nature of these open materials means that anyone can legally and freely copy, use, adapt and re-share them. OERs range from textbooks to curricula, syllabi, lecture notes, assignments, tests, projects, audio, video and animation."  



The open movement is based on the desire to make education widely accessible by providing free access to materials.
