The Anchorage paper reports on Wasilla’s librarian:

“Sarah said to Mary Ellen, ‘What would your response be if I asked you to remove some books from the collection?” Kilkenny said.

“I was shocked. Mary Ellen sat up straight and said something along the line of, ‘The books in the Wasilla Library collection were selected on the basis of national selection criteria for libraries of this size, and I would absolutely resist all efforts to ban books.’”

How are the ‘national selection criteria’ formulated? I suspect that librarians as a profession are as scrupulously apolitical as, say, teachers or social workers…

This Volokh commenter asserts that librarians can and do ban books and it’s usually very easy: they don’t buy them. No one makes a fuss unless the book is a bestseller.
