Interesting, and Disturing, Editorial About Some Library Practices

What is the purpose of a library? I always thought it was place to check books out from, but I never thought about what sort of policy a library follows in choosing what sort of books to retain.

Probably why the best library I ever used was this one.

Seriously, I think that I basically agree with the editorial. Libraries should not be concerned about which books are popular, so much as making available the widest possible selection to the community.
