Library Certification Due March 31, 2026

Illinois Heartland Library System

Published : Jan. 7, 2026

To remain or become members of a regional library system, Illinois libraries are required by statute to annually certify that they comply with the membership criteria set forth in the Illinois Administrative Code (23 ILAC 3030.200). In conjunction with this certification, all libraries must also complete the ILLINET Interlibrary Loan Statistical Survey.

The window for certification opened on Friday, January 2, and will remain open through Tuesday, March 31. You will certify through your library’s account in the Library Directory & Learning Calendar (L2). We recommend that you complete the ILLINET Interlibrary Loan Statistical Survey before you begin the certification process. The due date for the ILLINET survey was moved up to December 31, 2025, but you can still complete it by March 31, 2026, at Counting Opinions

For more information about the certification process and completing the ILLINET Interlibrary Loan Statistical Survey, refer to our Annual Certification & ILLINET Traffic Loan Survey page.
