The irony here is that my university quietly "delisted" a bunch of books from far-right extremists (Ann Coulter, Bill Oreilly, Jordan Peterson) but then launched protests over banned books in schools.
But I just went to their online catalogue to confirm if that's still the case - of all the authors mentioned, I could only find a single copy of a Jordan Peterson book in a psychology library at a satellite campus. Interestingly, they have a dozen books about Jordan Peterson (both pro and anti, interestingly enough).
Although it's worth pointing out that the article only considered external acts as "banning". Actions of librarians to maintain their collections are not considered censorship and are not publicly tracked anyway.
