Nowadays,it is the country - level libraries that restrict the development of the public libraries in our country. What the county - level libraries need to resolve fast is the problem of service ability. And the jumping -off point, or rather the key, is to support the literature purchase fund from the angles of system and poli- cy. In the light of China＇ s present economic strength and the financial support priority the government has to stick to, it＇ s unrealistic for the villages and towns libraries to get sufficient support. As a result, at the present stage, the mode of the villages and towns libraries which may be first promoted is that： the county libraries off comprehen- sive,extensiv and standardized mobile library service for the village and towns librari and to promote the fusion of the villages and towns libraries targeted to the public and to the student of the elementary schools and high schools.
