The length of borrowing time is usually determined by the relevant regulations formulated by the library. Different libraries and different types of books can have different lending time regulations. For example, the general borrowing time of books is one to two months, while the borrowing time of some information or technology books may be one or two weeks. Before borrowing books, readers should go to the library to understand the relevant regulations on the length of borrowing, so as to return the books in time and avoid possible expenses such as overtime.
The regulations on the length of borrowing time have also gradually evolved. In some places, libraries began to gradually realize all-weather library services, cancel the restriction on the length of borrowing time, and implement the free borrowing mode.
