The major role a public library plays today is a culture center as well as a learning center, other than as an information center. In this paper, the author tried to share the visiting experiences of public libraries from Singapore and the plans to improve the operating space and public libraries in Taiwan. The library literature showed that the perfect architecture design is the most important point in management of libraries. The clarity of directions, the comfort of bright and roomy spaces, the perfect reading environments, the excellent family reading areas for parents and kids are key concerns. After exploring space imagery and the importance of human caring, the design trends in the development of the library were illustrated and then recommendations were made for the reference of participants.
