Mary Titcomb was the first librarian to lead the Washington County Free Library, the first county library chartered in the United States. She was dedicated to seeing that the library was accessible beyond the county seat, so she developed the first Book Wagon. This horse-drawn carriage traveled to rural destinations of Washington County, reaching readers who otherwise would not have the capability to visit the library. See how Mary Titcomb’s work in Washington County went far beyond the circulation of books.
