There is a difference between reading and learning. When I read, that's exactly what I am doing.
When I need to learn something, I might read, watch lectures, do tutorials. If I am reading "Art of Computer Programming" for fun, then I would say that I am reading. But if I am reading it for learning, then I would say I am working or studying.
