"Harvard’s Libraries and Museums" is an academic travelogue that systematically introduces Harvard’s libraries, museums, and their culture from the perspective of libraries and museums. Libraries are the core of universities and campus culture in the United States. Libraries are not only places for borrowing and returning books, but also reading rooms for students and offices for scholars. During his ten-month stay as a visiting scholar in the Department of History of Science at Harvard, the author, Tian Song, visited Harvard and nearby libraries and museums extensively for work and personal interests. He recorded relevant information, personal insights, and took photos, which were compiled into this book.
