EI Clearinghouse Library materials should be returned through the Illinois Library Delivery Service (ILDS).

If a patron returns EI Clearinghouse materials to your library, and your library is not a direct delivery location on the Illinois Library Delivery Service, just attach the ILDS routing slip with a rubber band to the item and return it through your regional delivery system.

  • You can print ILDS routing slips
  • The Illinois Heartland Library System Champaign Office code is ZCH.
  • The Early Intervention Clearinghouse ILDS code is IEIS.
