[Libraries] … do not exist for free. They cost their communities—whether composed of taxpayers, tuition-payers, donors, or a combination—a substantial amount of money. It’s well-intentioned to emphasize that libraries provide materials and services without exacting immediate payment from users for each transaction. But today it is at best a mistake and at worst self-destructive to underrepresent the considerable ongoing investment that the members of a community make to have library collections, technology, personnel, and facilities available to them. …Rather than promote the “free library,” let’s remind our communities of their great investment and of the tremendous wealth of returns they derive from that investment: materials, specialized assistance, and programming.
