Does your library have members?

In the most recent American Libraries newsletter, there was a link to a blog post about a talk at the recent American Library Association convention. "Patron" or "Customer"? Consultant Makes the Case for "Member". What a brilliant idea! That way everyone is part of a club. No one wants to be patronized, and we all know that customers are not always right, especially when they habitually claim that their late items were actually on time. It's a simple idea, but I've never heard it before, not even when we were discussing it in library school. Members have cards, and people who aren't members are guests. They pay dues in the form of taxes.
