The document discusses the benefits and challenges of open educational resources (OER). The benefits include cost savings for students, setting a good example of using open resources and attribution, allowing flexibility to use a variety of sources for class content, and saving time by not needing to update materials with new editions. However, challenges include links to online resources becoming broken, the significant time required to search for materials, uncertainty about the accuracy and quality of sources without careful review, loss of consistency from standard textbooks, and reliance on technology where technical issues could disrupt access to resources.
