How to Apply

Apply for a library card online

Library card application forms are also available at any branch, or you can print out a form (in English or Spanish) and bring it with you. Your card will be issued while you wait.


What do I need to get a library card?

  • Photo I.D. – a valid Driver’s License or other official photo identification
  • Proof of current address – if your current address is not printed on your photo I.D., then you also need a document with your address: e.g. bank statement, utility bill, imprinted check, rental agreement, rent receipt, or canceled mail with name and address. If you have recently moved and cannot verify your new address, we can send you a postcard in the mail to use as your proof of address.

If you cannot provide proof of your address, you can still apply for an Internet Only Card. This type of card gives you access to the library’s public computers, but cannot be used to check out materials.

If you are an out-of-state visitor, you can apply for a Visitor’s Card for $10 for 3 months.

If you are under 16, your parent or legal guardian must come with you to the library, and bring their photo I.D. and proof of current address. The parent or legal guardian is responsible for items checked out on the child’s card and any related fines and fees. Notice to parents.


Lost or Stolen Cards

If your library card is lost or stolen, please report it immediately by phone or in person at any branch.

You are responsible for any materials checked out on your card until the card is reported lost or stolen.

To get a replacement card, you will need to bring your photo I.D. to any branch. Replacement cards are $1.00 for adults.


Expired Cards

Library cards automatically expire every 5 years, so that we can confirm we have your current address and phone number. If your card has expired, you may renew your card by contacting your local library.


Library PINs

A PIN is a secret number or password that you create yourself. You can create your PIN either online or at any branch, with your library card. Your PIN should be between 4-30 letters and/or numbers.

To create a PIN online:

  1. Click on the “My Account” link at the top of our website to go to the MARINet login screen.
  2. Type your name and your entire library barcode number (starting with “211110…”), but leave the PIN box blank and click Submit.
  3. On the next screen, re-type your barcode number and enter a PIN in both boxes, then click submit.

If you forget your PIN:

  • If we have your email address on file, you can request a new PIN online.
  • You can also reset your PIN at any branch. Be sure to bring your library card with you.
