In this study, examined are the characteristics of ‘One Book, One City’ reading campaigns conducted in Seattle, Chicago, and ‘The Big Read’, a nationwide ‘One Book’ campaign, supported by the NEA, in the U.S.A. and Seoul and Cheongju in Korea. Some differences as well as similarities were found in the goal setting, selection of books, strategies for reading and discussion, and programs of these ‘One Book’ reading campaigns. While, as a mass reading event, ‘One Book’ reading campaigns in various communities share the goal of promoting literacy and communication through reading and discussion, each ‘One Book’ campaign seems to show uniqueness in the criteria of book selection, reading and discussion guides, and the activities and programs, which make up cultural contents.
