This paper, firstly, examined the contents of 39 cities’ current public library strategic plans in the United States and, secondarily, clarified the features of building renewals specifically in line with local authority’s strategic goals through the case study of Boston Public Library (BPL). It mainly turns out the followings: firstly, BPL efforts to serve more spaces for users, particularly teenagers and children, rather than book collection; secondarily, BPL renews not only physical spaces but also library’s programs collaborating with local people; thirdly, BPL actively utilizes existing buildings in addition to new construction, depending on the sustainability of public resources.
