This is another library that had a huge addition. Carlisle, Middlesex Co., Massachusetts is a very small town, but their Library, the Gleason Public Library, was one of my favorites. Librarian spent quite a bit of time with me, and took me to the old section of the Library.
Books about Carlisle. (Above and two photos below.)
The old section of the Library is upstairs, under lock and key. Doesn't appear to be used for anything other than light storage.
Lovely woods behind the Library.
