Curation is part of the job for librarians, and it's a specialized skill. I don't have to agree with an ideology to accept what they do is curation - a Librarian in a Taliban library still curates their collection regardless of my endorsement of Sharia. If they are instructed by Kabul to remove specific texts, then it's a ban.
