From the Illinois State Library:
"The Illinois State Library's Electronic Resource Exposition hosted at the Schaumburg Township District Library promises to be an eventful exposition. The 2009 ER-XPO features vendors who have participated in Try-It! Illinois 2009. The day will provide opportunities for one-on-one consultations with vendor representatives, as well as Q & A focus sessions with individual vendor presentations in a lab setting. There is no charge to attend ER-XPO. Registration for this signature event is suggested but not required."
