What is Library Mail used for?

• A. Mailings to libraries and items intended for library use (subject to restrictions)
• B. Library materials for personal use only
• C. Packages to residential addresses
• D. International shipments

Answer: (A)

Library Mail is a USPS service designed to move library materials and related items at a reduced rate, specifically between libraries or to a library for use. This means shipments like books, journals, microfilm, and other materials intended for library use (and equipment used by libraries) can travel under Library Mail, as long as they meet the eligibility rules. There are restrictions: the shipment must be going to a library or other qualified institution, the contents must be library materials or equipment for library use, and items that are for personal use or contain advertising aren’t eligible. It’s also a domestic service, not intended for international shipments. So the best answer is mailings to libraries and items intended for library use (subject to restrictions).
