Dear John, 

For many OCW users like Elizabeth, learning is a lifelong pursuit that is different for each of us. OCW helps empower learners by removing the traditional barriers that limit when and how we can learn.

That’s why it’s important that OCW resources are here every day for learners whenever they need us, and whenever they are most inspired to learn at their own pace. If OCW has been a valuable resource to you, we hope you’ll consider joining other learners around the world in making a gift to OCW before 11:59 pm EDT today as part of MIT’s 24-Hour Challenge.
