The Boston Public Library moves into its new building in Boylston Street
After four years of impressive growth since its founding in 1854, the Boston Public Library moved into its new building on Boylston Street. The Library outgrew this building within thirty years and moved again, on its way to becoming the largest municipal library system in the United States. (By John Osborne)
