This post contains a collection of places which offer free online learning. Yesterday, I accessed Yale Open Courses and discovered 7 history classes in various formats, including transcripts in html. For a deaf person, icing on the cake!
If you're looking for fun and excitement, poking around here might lead to discoveries!
