In this series of four essays, Richard J. Cox explores the social and professional ramifications of 9/11 on our information landscape. 'Musing,' written on the first anniversary of the terrorist attacks, looks back at a year of change and commemoration. 'Reacting' examines the impact of 9/11 on a department of information sciences. 'Preparing' is a cogent argument for the need to rethink current disaster and contingency planning practices. 'Teaching' focuses on the author's experiences developing and teaching a doctoral seminar on the role of the information professional in a post 9/11 world.
