Branch library system In the latter half of the 19th century, the library worked vigorously to develop and expand its branch library system. Viewed as a means to extend its presence throughout the city, the branch system evolved from an idea in 1867 to a reality in 1870, when the first branch library in the United States was opened in East Boston. The library currently has 25 branches serving diverse populations in the city's neighborhoods.
