Library Cards are free and there are no residency requirements. You must, however, have identification with your name and current address. Identification can be a driver's license or an ID card issued by the DMV.
If you don't have a driver's license or ID card, you should present two of the following, one of which must have your current address: Printed personal check, credit card, rental or property tax receipt, or business mail with current postmark. If you are under the age of 18, identification is not required; however, your parent or guardian must sign the library card application.
