Abstract: Based on a brief review of the collection and services of communist documents (also known
as “red” documents) in grassroots public libraries, this paper introduced the history and achievements
of East-river Column documents collection in Dalingshan library and discussed its practices from three
aspects, namely, digitization and knowledge graph development, exhibition center, and document mining
and service innovation. The paper proposed that the grassroots public libraries should emphasize local
characteristics, prioritize services, innovate both online and offline services, and encourage readers to tell
revolutionary stories, so as to better play the vanguard role in promoting the red culture.
