The public library is a public welfare cultural service position that open to all citizens of the society.The ultimate goal of its establishment is to open up the vision of citizens，meet the needs of citizens for cultural knowledge，and fundamentally improve the cultural knowledge content of citizens.However，with the socialist era with Chinese characteristics entering a new era of development，the main contradictions in our society have been transformed into contradictions between the people's growing needs for a better life and unbalanced and inadequate development.The public library at the county level highlights the problem of lack of talents.The main reason is that the construction of the talent team cannot support the function of public cultural services.Taking the current situation of talents team building in county-level public libraries as an example，this paper comprehensively explores and analyzes the problem of talent construction in libraries，proposes the policy recommendations，such as transforming personnel mechanism，enriching the talent team，innovating the government to purchase service mechanisms，encouraging social forces to participate，increasing the funds for talent security，and improves talents' work enthusiasm and subjective initiative；linking “competent department-financial department-expert team” so as to establish and improve the talent evaluation system and so on.
