Illinois Heartland Library System (IHLS) Delivery Service is provided to support resource sharing among Illinois libraries. Our team ships 6.4 million items annually between IHLS member libraries and through Illinois library resource sharing networks.

IHLS Delivery service consists of three regional hubs, each serving a specific geographic area. Find your library's IHLS Delivery Hub and operations manager on our Hubs page.


Want to know what IHLS Delivery route your library is on? Find this--and other libraries along the same route--on our Routes page. Routes vary each day and change periodically.

Unidentified Items

Are you missing an item? Does one of these items belong to you? This page lists items that are at one of the IHLS hubs and have no barcodes or other identifying information.

Delivery On the Go: Same-Day Delivery for Downstream Libraries

Delivery On the Go (DOG) is where a library on a downstream route has requested an item from an upstream library. If tagged for DOG delivery, that item may be able to be delivered later that very same day. DOG deliveries are only available if that library is on the same route as your library and delivery is scheduled to arrive at the receiving library later that day.

Delivery Guidelines

For quick and efficient interlibrary delivery service that keeps both library items and library and IHLS Delivery staff safe, IHLS libraries are asked to abide by a set of Delivery Guidelines.
