All are welcome in the Tower Hill Library found on the lower level of the Stoddard Education and Visitors Center and members may borrow books. The Library has more than 8,000 resources including books, magazines and dvds on gardening for all ages and abilities. The Library is a great space for reading, quiet study and research. We also offer a children’s area with puzzles, drawing materials and a comfortable couch to sit and read a favorite story.

Tower Hill Botanic Garden opened in 1986 but its history as the Worcester County Horticultural Society dates back to the 1840s, and the Library goes back almost as far. Early library holdings began with donations from founders and members, and today the Library provides access to institutional and garden history records and regularly exhibits materials from our archives.
