Are universities closing down open access to lectures and course notes?
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?
Depending on the country, this may well be related to the fact that professors sometimes have to expect copyright warnings if excerpts from other sources are used and republished in the teaching materials. Therefore, some things are only available to enrolled students.
