Library cards are issued free of charge to county residents age 16 or older upon a presentation of a photo ID with a permanent address. Cards may be requested at any library branch in our library system. If your photo ID does not show your permanent address, please bring separate proof of address within the county, such as a utility bill, bank statement, rent receipt in your name, etc. Those younger than 16 requesting cards must have a parent or guardian accompany them to sign the application form.
