Children Reading Area

The Mount Arlington Public Library has dedicated the children’s reading area to former Mayor, Mary Johanna LoPonte.  Johanna was a lifelong educator and public servant who worked passionately to improve this town and create a modern community which included the building of a new library.

It is appropriate that the children’s reading area be dedicated in her name as it is a living memorial to her memory in bringing education and literacy to the community.

Greetings from the Library Director


Happy Spring Everyone!

Finally, longer days and warm sunshine are wonderful incentives for enjoying every day of this beautiful season. I love to look for buds and early signs of daffodils and hyacinths peaking up from the earth, and the little critters that frequent my home garden. I have always done this as a little girl and continue to do so today.

I also enjoy seeing the beautiful arboretum of plants and shrubs on the library grounds come to life and bloom. I welcome all the creatures that come to the library grounds for sanctuary. We have a resident fox, a coyote, wild turkeys, chickens, ground hogs and a red tailed hawk. We have also rescued garter snakes and earthworms from a horrible demise in our parking lot. This year I hope to put out some birdhouses for the finches we have and look forward to the butterfly bush welcoming our pollinators.

This is also a wonderful time to get outside and make use of the cornucopia of services that Mount Arlington provides. Please stop by the library to participate in our variety of services, and to borrow our AV offerings. We also offer movie showings and clubs for children and adults.

In addition to our extensive collection of fiction and nonfiction books, British, TV Series and movie DVDs, we offer NJ Advocates for Aging Well programing in support of the Mayor’s wellness Campaign. This service offers support for adults that include free webinars in our Media Room, information on SNAP, General

Assistance, Housing and Utility Assistance.

We are not just “books”, rather, we are a community resource that is open for all areas of public outreach and communication.

Please take the time to stop by and visit with us. Tina
