There are some computers around the lobby on the first floor of the library for readers to inquire. Click on the browser, and you will go directly to the home page of the library. There is a "Reader Query" on the upper left, then click "Bibliographic Query", enter the book or content or author information to be queried, and click Query to display the number of books in the library and the number that can be borrowed. Remember the "call number", go into the library and look for books according to the number, and then at the library gate.
