It is located at 299 Main Street, in an architecturally significant Queen Anne building constructed in 1895 with funds given by the library's major benefactors, David L. Aldrich and Edwin Milner.

[1] The Aldrich Free Public Library stands in the village center of Moosup, at the northwest corner of Main and High Streets.

[2] The library was built in 1895 to a design by Charles F. Wilcox of Providence, Rhode Island, and is a prominent local example of Queen Anne Victorian architecture.

It was funded in part by a bequest of David Aldrich, a local mill owner, and his business partner, Edwin Milner.

Milner donated the land on which it stands, and covered enough of the building construction cost so that the locally raised funds could be used for books and furnishings.
