In the article librarians talk about the normal process of weeding out old books, duplicates of rare accesses, etc.
The article itself contrasts that with school boards directing librarians to remove far more than tha regular weeding.
The boards set policy that the librarians are compelled to follow or risk being fired.

It's dispiriting to see librarians distort a normal process (deaccession) to cover up their own book banning.
