From the Illinois State Library newsletter:

The Illinois State Library is in the final stages of the process to select a vendor to maintain data collected for the Illinois Public Library Annual Report (IPLAR) and Illinois Library and Information Network (ILLINET) surveys. At this time, Illinois libraries should not complete their online FY11–12 IPLAR or ILLINET surveys. If you have begun completing these surveys online for submission, or if you have any additional questions, please email Robert Jones (IPLAR) or call him at 217-785-1168, or email Gwen Harrison (ILLINET) or call her at 217-785-7334.
