Is the maximum weight limit for packages sent via Media Mail greater than that of Library Mail?

The maximum weight limit for packages sent via Media Mail exceeds that of Library Mail, making it the correct answer. Media Mail is designed to provide a cost-effective way to send educational materials, such as books, CDs, and DVDs, with a maximum weight limit of 70 pounds. In contrast, Library Mail is primarily for the use of libraries and is intended exclusively for sending books, periodicals, and other educational materials between libraries and library patrons, with a maximum weight limit of 15 pounds. This significant difference in maximum weight limits clearly indicates that Media Mail can accommodate heavier shipments compared to Library Mail.
