The Louis B. Goodall Memorial Library is a one and one-half story Georgian style Colonial Revival brick building designed by the Portland architect William O. Armitage in 1937. It was built with funds donated by Dr. and Mrs. Harvey Thornburg, the daughter of one of the Town?s most noted residents, Louis B. Goodall. The building is owned by the Town of Sanford and administered by a Board of Trustees. Although substantially enlarged in 1976, the addition was positioned in a manner that allowed the richly embellished front portion of the building to retain its integrity of workmanship, design, materials, setting, location, association and feeling. The library was entered into the National Register for its role as a significant local educational facility and for the quality of its architectural design.
