For those still on the fence about whether academic suppression is a “new” thing or (as I believe) has been around for quite some time, here are some other reads:

Some of these articles illustrate specific cases, others encourage further reading, but I think my end conclusion would be that categorising academic suppression as a “new” thing, or something exclusive of one particular field or political ideology is wrong, and we of hope to maintain academic freedom, we’re best served not ignoring history, but learning from it.
