The development of red literature resources in public libraries mainly falls into two categories: resource construction and reader services. The primary methods for the construction of red literature resources in public libraries include collecting and organizing red literature resources, constructing red service spaces, producing special documentaries on red themes, and establishing red databases or platforms. Reader services for red literature resources in public libraries mainly consist of hosting red literature exhibitions and lectures, promoting red reading, and organizing theme-based public and educational research activities. Useful explorations in developing red literature resources have been conducted by the Shandong Provincial Library, Taiyuan City Library in Shanxi Province, Xiangan District Library in Xiamen City, and Dalingshan Library in Dongguan City, Guangdong Province. Strengthening literature awareness, developing planning, highlighting regional characteristics, creating thematic collections, exploring the content of the resources, enriching service models, and leveraging digital enablement to provide specialized services, are the evolving strategies for the development of red literature resources in public libraries.
