Westerly, RI
Opened in 1894 as not just a library but a museum, bowling alley, gymnasium and meeting place for the Grand Army of the Republic. Many renovations have taken place over the years. The most recent in 1994 doubled the size of the building. It has a tremendous amount of space. The art gets rotated regularly in the great room. The library is located next to the Wilcox Park which is also worthy of a visit. A cottage is provided to an artist in residence.
One of the most recent additions to libraries is the library of things. Notice how organized theirs is in the third picture. https://www.westerlylibrary.org/history
