Get a Library Card

Marin County residents of any age can register online for a full access library card.

At the end of the successful online registration process, you will receive a library card number and PIN. You can immediately use it to log into the MARINet site to search the catalog and access any of our eBook collections and shared MARINet digital resources.

If you prefer to have a physical library card, you can pick one up in person at the circulation desk.

Don't have a residential address in Marin County? Visit any public library in Marin to get a card in person.

If you can’t find your library card, or aren’t sure if your account is still active, please email circ@cityofmillvalley.org. Our staff can verify the status of your account and get you your barcode number.  

A PIN/password is required to login and manage your account and access digital content from home. Instructions for setting up a PIN or resetting your PIN can be found online.

Please note: Resetting your PIN will send an email to the address in your library record. If you no longer have access to that address, please email circ@cityofmillvalley.org for assistance.

Children and adults may both use our online forms to sign up for library cards. Please see "How do I get a Library Card?" FAQ for links to our applications.

Processing new cards requires a little work on our end. During normal business hours we are able to process most cards within an hour. If you've signed up for your card after 5 pm or on a weekend, it might take a little longer. Please email circ@cityofmillvalley.org with your name and barcode number and we will get back to you as soon as possible with the status of your account.

Some resources, including hoopla, Kanopy, and LinkedIn Learning, need to be signed up for using your specific home library. If you live in unincorporated Mill Valley, you may need to specify a different library. Check your home library here.
