The library space has historically been influenced by the change of its information and social environment. This paper describes the effect of ubiquitous environment on the library's space, by literature review, case analysis. and focus-group interview of 5 undergraduate students. The results show that the library's physical place is still important for users, and suggest the library information space design and management need to reflect the open-ness and the interactive-ness of the ubiquitous space.
