Delivery Routing Slips

Routing slips should be used when a slip is required for delivery purposes and is not available via your library’s ILS. Please make sure the name on the routing slip matches the name in the yellow column on the Delivery Index. If this information does not match, your item(s) may not be directed to the proper library and will be re-routed.

For additional information on labeling please refer to the Delivery Policies page. For more information on routing slips, please visit the 'Sort-to-Light' page.
