Ask HN: Are universities closing down open access to lectures and course notes?
11 by hwers | 2 comments on Hacker News.
7 years ago or so it seemed like you could find invaluable learning for free by just looking up free university lectures or course notes at any arbitrary school. Today when I try look it up they almost universally seem closed down behind password protection (as if coordinated by higher order). I haven't heard people talk about this, am I the only one noticing this pattern?
