Whenever the library is open, the library staff is here to help you--just come to the Information Services Desk on the main level.
Use the link above to send a question to a librarian via email. We'll try to answer your question within 24 hours. Keep in mind that if you have a complex research question, you'll probably be able to get a quicker and more complete answer by coming in to the library instead.
If you can't come into the library, please don't hesitate to call the library's Information Services Desk at (630) 637-5715. Or, if you'd like to talk to a specific staff member, please see the library's staff directory.
Contact a library subject specialist via library Facebook pages.
