Constructed of yellow tapestry brick, with Indiana limestone columns and Vermont stone foundation, Bixby Memorial Library is designed in classic greek Revival style around the central rotunda, with a stained glass dome overhead and four sets of three hollow steel columns covered with scagliola (to resemble marble) at the four corners of the rotunda on the first floor. Entering the building through heavy oak double doors, one stands in the rotunda, the large reading and reference room tothe left, the children’s room straight ahead and the main desk, stacks, mezzanine and Lois Noonan Vermont Room to the right. A marble staircase rises on both sides above the front entrance, leading to the second floor rooms and inner balcony. Accessed by three pairs of double doors in the reference room, the west-facing porch overlooks Otter Creek and the Adirondacks.
While contents of the two first floor display cases are changed monthly, permanent exhibits upstairs include the Bilhuber Native American Collection, local projectile pts, and military artifacts from the American Revolution and Civil War. Nineteenth century portraits, including one of William Bixby, paintings by Vermont artists, etchings by Luigi Lucioni, local engravings and lithographs, and historic photographs are hung throughout the building. "The Young Trumpeter,” sculpted by Margaret Foley, models of historic ships, and other works are found on the first floor. Two collections are displayed to the right and left of the community room.
The Bixby Memorial Free Library is listed on the National and State of Vermont Historic Register.
