It is located at 435 Main Road in the village center, in an architecturally distinguished 1915 Classical Revival building designed by John Calvin Stevens and John Howard Stevens.

[1] The John B. Curtis Free Public Library is located at the crossroads that defines the rural village center of Bradford, a rural community north of Bangor.

It is a modest single-story masonry structure, built of brick and set on a raised foundation of rough-cut granite.

The transition from the vestibule to the main room is marked by a Colonial Revival arch, which is echoed in the framing of the fireplace on the opposite wall.

[2] The library was built in 1914–15, with funding from a bequest by John Bacon Curtis, who was raised in Bradford and made a business fortune developing machinery for the shaping and packaging of spruce gum.
