The library value calculator was originally developed by the Massachusetts Library Association. Our version was adapted from Maine State Library's Library Use Value Calculator.

The library value calculator uses a combination of actual and estimated average costs of library materials and services as well as actual and estimated average costs for equivalent or comparable services available elsewhere in the Worthington community.
