This study proposes to analyze the concept and introduction of infinite creative space (makerspace) to redefine the roles of existing library spaces. This study also attempts to formulate a suitable program for public library makerspaces by analyzing case studies. Literature review and case study methods are used for deriving the makerspace concept, the evolution of makerspace, the implications posed by makerspace operation domestically and abroad, and the utilization of makerspace. Finally, we suggest story creation programs, topic-based programs reflecting the library characteristics, professional mentoring programs, expert consulting programs, various training programs, patent application support programs, incubator programs, and so on.
