The Library has notaries public on staff. We recommend that you call us at 708-547-7393, ext. 3 to make sure a notary is available at the time you plan to come. We will notarize most documents except real estate and immigration documents.  This service is free. Please bring your government-issued identification and documents. Documents must be signed in front of the notary.  All people signing the document(s) must be present.
