Renewing Items

After logging in, scroll down to the section "Items Checked Out," where you will see a list of the items currently checked out to you, along with their due dates. This is the easiest way to keep track of when you will need to return or renew the items you have checked out.

In order to renew items, simply click the checkboxes next to the items you would like to renew, then click Renew Items.


  • If you are unable to log into your library account, please contact Circulation Services at 847-491-7633 or
  • If you are able to log into your account but are unable to renew  your items, there may be a block on your account. Check the blockssection to see if:
    • You have an overdue recalled book; and/or
    • You have reached or exceeded the maximum allowed fine/fee limit.
  • If you are able to renew some items but unable to renew others:
    • You may have reached your consecutive renewal limit*; or
    • The book may be requested by another user.

*Borrowers with a one-year loan may renew books consecutively twice; borrowers with a 4-week or 12-week loan may renew books consecutively three times. Once the consecutive renewal limit is reached, the items must be brought to the Circulation Desk. Items may then be checked in and immediately checked out again on a new loan with a fresh renewal cycle, as long as no other user has requested them.
