The Boston Public Library encourages visitors to access this vast collection, as some of the materials would only be accessible to research scholars anywhere else. They allow patrons to view this items through exhibits within the library The BPL has many different components: The central library, 24 branches, map and business centers, as well as their website--that offers may resources like the catalog. According to the BLP website, the Central Library in Copely Square contains five significant elements: Bates Hall, The Chavannes Gallery, Library Tours, The Abbey Room, and the Sargent Gallery. All areas listed have beautiful architecture, with murals lining the walls and arched ceilings. The Chavannes Gallery is a collection of murals by French painter Pierre de Puvis Chavannes, while the Abbey Room contains murals lining the walls and a French marble fireplace. The library tours last about an hour and visitors can see the whole Central Library and learn about architects, Phillip Johnson and Charles Follen McKim.
Soon after the library's establishment, the library collection of 16,000 volumes grew out its first location on Mason Street, and therefore in 1895 it was relocated in a new building on Bolston Street. The new building was designed by the architect Charles Follen McKim. Since its completion the building was expanded two times, with two new additions: the first designed by Joseph McGinnis, constructed in 1918 and demolished in 1971 for the construction of the second addition, designed by the architect Philip Johnson. Some of the most interesting items within the collection specifically are first folio editions of William Shakespeare's works as well as original music scores from some famous composers like, Mozart.
