I totally agree. People who want evergreen classics count too, and the library should do its best to ensure they can get the books they want as well. They shouldn't stock nothing but bestsellers, any more than they should stock no bestsellers at all.

And, with the Internet (e.g. Gutenberg), evergreen classics are less of an issue. Speaking for myself, I've gotten rid of most of my books in the public domain unless they have other characteristics like illustrations that make me want to hold onto them.
