The public Reuben Hoar Library.

The library was named after Reuben Hoar, a prominent lawyer and statesman who was born in Lincoln, Massachusetts, in 1772. He served as a member of the United States House of Representatives and the United States Senate, as well as a justice of the Massachusetts Supreme Judicial Court.

The library's origins can be traced back to 1886 when the Littleton Library Association was formed. The association was composed of local citizens who recognized the need for a public library in the town. They raised funds and acquired books to start a library collection.

In 1893, the Littleton Library Association secured a grant from the state of Massachusetts to build a dedicated library building. The current library building, located at 41 Shattuck Street, was constructed in 1893-1894 with funds from the state grant and additional donations from local residents.

The library building was designed in the Richardsonian Romanesque architectural style, which was popular during the late 19th century. It features a distinctive red brick exterior, arched windows, and a prominent turret. The building's design was attributed to architect Arthur G. Everett.

The Reuben Hoar Public Library officially opened its doors to the public on November 1, 1894. It served as a center for educational and cultural activities in the community, providing access to books, newspapers, and other resources.
