Textbook costs have soared more than 800% since 1978, at more than four times the inflation rate. Student loan debt surpassed credit card debt for the first time in 2010. One study showed that 65% of students don’t buy textbooks due to the cost; other studies have recorded even higher percentages.
A growing solution to this problem of spiraling textbook costs is Open Educational Resources (OER): textbooks written and peer-reviewed by experts / academics and made available freely online. Often OER collections are the result of a foundation-sponsored initiative. Below are well-regarded, robust OER collections.
