The HathiTrust Digital Library has scanned over 3.5 billion pages of text and made a significant percentage of them available for viewing, printing, and downloading for free. You can search by title, author, subject (e.g. China or Chinese), and keyword; and limit your results to "Full view.". Some results will display titles in Chinese.
The following ranges of call numbers will help you browse in the Reference collection (1st floor) and in the Circulating book collection on the 3rd floor. Books in Silver Special Collections, e.g. in the Wolfgang Mieder Proverb Library, must be used there, and you need to make an appointment. Books at the Library Research Annex or Williston Annex must be ordered online. Other restrictions may apply.
