Abstract: Against the background of building “double first-class” universities, the subject service provided by the “double first-class” university library has become an important task for the library to align with the construction of first-class programs in universities. The university library should re-examine the present situation of subject service, find out the problem and make improvement, so as to support subject construction deeply. This paper investigates the current situation of subject service in 42 “double firstclass” university libraries from four aspects—subject service column, subject librarian, subject service content and subject service platform—by online survey. The survey results are analyzed in detail, which lead to four recommendations, namely, to improve the relevant programming on subject service, optimize the position and number of subject librarians, deepen discipline service, and building first-class discipline service platform for first-class disciplines.
