Abstract: Space design has become a necessary requirement for higher quality development of libraries. The paper elaborates on the dialectical unity view in library space design, including universality and uniqueness, holistic and internal and external views, professional and non professional views, static and dynamic areas, and infinite possibilities of spatial design functions. The paper discusses and analyzes at least ten elements of library space design, including macro dimensions of urban landmarks, artistic

interpretation, cultural inheritance and internal and external interaction, meso dimensions of professional symbols, color material selection and green low-carbon, and micro dimensions of furniture design, lighting and safety care. The paper points out that the new space design scheme for smart libraries is becoming a development trend.
