. . . get a library card
If you are an adult, come into the library and bring your Michigan Driver's License or Michigan ID showing your current address. Fill out a registration card and acquire your library card.
If you are under 18, come into the library with your parent or guardian. You will fill out the front side of the registration card. Your parent or guardian will fill out the back side of the registration card and present their Michigan Driver's License or Michigan ID showing your correct address. Then you will have your library card.
