       【乙】予初十日到郡，连夜游虎丘^①，月色甚美，游人尚稀，风亭月榭间，以红粉笙歌^② 一两队点缀，亦复不恶。然终不若山空人静，独往会心。尝秋夜坐钓月矶^③，昏黑无往来，时闻风铎^④，又见佛灯隐现林梢而已。及今年春中与无际偕访仲和^⑤于此。夜半月出无人，相与坐石台，不复饮酒，亦不复谈，以静意对之，觉悠然欲与清景俱往也。生平过虎丘才两度，见虎丘本色耳！

Thomas Bray began the first free lending library in the late 1600s. He set up more than 30 or these libraries in the American colonies. However, the idea for this kind of free library ended when Bray died in 1730. In 1731, Benjamin Franklin and some friends started the first subscription（订阅费） library in the United States.
