Funds
Funds for the new library were primarily recognized by two anonymous donations; the first for $75,000 to be used for an art center and the second for $175,000 to be used for the library. The Trustees wasted no time and ground for the library was soon broken. The contemporary style building was designed by Rich and Tucker Associates and it was to be named for Stacy Baxter Southworth, a former Headmaster who was beloved by the Academy.
Donations
The building was completed by March of 1965 and the collection of about 3,000 volumes that were in the auditorium was relocated to the library. Over the years donations were made in the form of books and money and by 1976 the collection had grown to about 125,000 volumes.
Art Studio & Gallery
The new art studio and gallery facilitated a new art program, developed primarily by Louise Pennock. That gallery featured work done by students, faculty, and local artists. The gallery became known simply as the Thayer Gallery.
