Greetings from the Library Director


Welcome to the Mount Arlington Public Library website.  We had a wonderful summer with many activities and programs, and are getting ready for a pleasant and colorful fall. 

I really enjoyed the activity in our reading garden.  The pollinators were busy making their rounds over the beautiful butterfly bushes. These hearty bushes require little attention, and can be enjoyed for their lovely blooms and resident yellow swallowtail butterflies and bumblebees.  The garden is open to everyone, and I invite you to sit on a bench to read or just relax and enjoy the sun.

The word “library” seems to be less associated with the quiet brick-and-mortar buildings we all grew up with, and more easily defined as vibrant and interactive spaces.

While providing all the usual services, libraries have become purveyors of intellectual,
informative and social services with the mission of educating, informing, and entertaining a variety of audiences.

I encourage you to stop by and spend some time with us.  Enjoy your day!


Library Card Eligibility

Who is eligible?

Free library cards are available to all residents of the Borough of Mount Arlington. Resident library cards are valid for three years and may be renewed with valid ID and proof of Mount Arlington residence.

Don’t live in Mount Arlington but still want a library card? Go to your local library (all Morris County libraries can be found listed on the MAIN website ( and sign up for a card with them. Then you will have access to the 49 libraries in the Morris County system, including Mount Arlington!

If you are a resident of Sussex County, you can get an open borrowing sticker from your local Sussex County branch, and then access Morris County’s library catalog. Please note that if you are an open borrower, you will NOT be able to place holds on items in the Morris County system.

What do I need to bring?

Bring photo ID of any kind (driver’s license, student ID, military ID, passport, etc.) that has your Mount Arlington address on it. If your license is not updated to include your Mount Arlington address, you will need to also bring a bill or statement with your current address.
