Someone still decides the book is not gonna be there, mostly for ideological reasons.
I guess if you agree with those reasons, it’s “curation”, if you don’t, it’s “banning”.
The practical difference is that, in one case, the taxpayers collectively decide what's appropriate for their children and what is not. In the other case, a single (or a few) individuals decide what is appropriate for all the taxpayers children.
I don't understand why some people think it's better to ignore the wishes of the voters.
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.
Someone decides what music gets played on radio and what the TV lineup looks like and calling that selection "banning" is reaching IMO . When the legislature is coming up with a blacklist, then it's blatantly "banning" to me
