Delivery

How the IFLS Courier System Works

• IFLS contracts with a courier (Purple Mountain Solutions, Inc.) to provide courier service to our area libraries.
• Purple Mountain does all the sorting of materials being routed to other IFLS area libraries.
• The Purple Mountain driver will drop off and pick up materials on your library’s scheduled delivery days.
• Purple Mountain picks up from and drops off at the IFLS office daily. All items labeled for IFLS or with the pink out-of-system routing labels which were picked up at the IFLS libraries will be sorted to the IFLS office. We unpack in the morning and send out-of-system materials with the 10 a.m. South Central pickup/delivery.
• The South Central Delivery Service has prepared a Wisconsin Delivery Network list that you can print out. If you do not find a library on the list, you will need to mail the material. For more information on sending Interlibrary Loan materials through courier, click HERE. 
• IFLS is the pick-up/drop-off point for all materials going to/coming from outside the IFLS system via the South Central Delivery Service.
