Donation is an important way that the library accesses literature resources. This paper investigates the present situation of library donation practice in provincial and sub-provincial libraries in China, and finds that the deficiencies of library donation are mainly concentrated on the old donation reward system and the lack of donation-soliciting system. According to the Public Library Law of the People's Republic of China, this paper proposes the corresponding solutions: the first is to implement the tax preferential system of donation; the second is to improve the donor-naming mechanism; and the third is to establish the system of library development fund.
