To work in libraries and university libraries above the municipal level, most of them need graduate students, but undergraduates generally don't need them. You don't have to be a graduate of library science or archival science, information science or information management to work in a library. English majors and computer majors can also work in the library, but their academic qualifications are also relatively high, and they are both graduate students. Since you like reading books so much, I suggest you consider the major of library science when you are in graduate school (the major of library science in Wuhan University, Zhong Da University, Sichuan University, Peking University, Heilongjiang University and Xiangtan University are all good). Go to the provincial library or university library after graduation.
Libraries generally have catalogers, consultants, information administrators and ancient book researchers, which are more suitable for your work.
If you want to work in a library after graduation, this is easy. You can directly search related information in Baidu or Google. The search term is "library" * "recruitment, and the time is limited to one week.
