[Purpose/significance] Public libraries work with communities to help reach more regions and populations with health information services, opening up the "last mile" of health information services.

[Result/conclusion] Public libraries and communities can start from the following four aspects to carry out health information services: improve the guarantee of
funds and talents, and strengthen the foundation of health service cooperation; based on the needs of the community, en⁃rich the content of health service cooperation; link the superior resources of both parties and innovate the way of health service cooperation; focus on marginalized areas and populations, and promote equitable access to health services.
