The Aldrich Public Library is the public library serving the city of Barre, Vermont. It is located at 6 Washington Street in the city center, in an architecturally distinguished Classical Revival building constructed in 1907–08 with funds bequested by Leonard Frost Aldrich, a local businessman, and was substantially enlarged in 2000. The building was listed on the National Register of Historic Places in 2016.
The oldest documented library in Barre was a small subscription library established in 1848. In 1873, the Barre Library Association was organized, as a formal subscription library stored in local businesses and homes. A second subscription library, the French Barre Library, was founded in 1887. These two collections were merged when the Aldrich Library was built in 1907–08. The Aldrich Library was made possible by a bequest from Leonard Frost Aldrich, a local businessman who had died without issue. His bequest included funding for construction of the building and the acquisition of books for its collection. The city council originally sought to have a building completely faced in local granite (the city's primary business), but this was found to be cost prohibitive, and a compromise construction of brick trimmed in local granite was developed by the architect, Penn Varney of Lynn, Massachusetts.
