This book shows the statistical data for censored content around the world by using typographic rules to design information. The type size of the name of the country indicates the population, and the tracking of the body text divides the country into three categories of 'free,' 'partially free' and 'not free.' The book uses the ZXX font which is designed to block optical character recognition. The percentage of content censored on the page is equal to the percentage of content censored in the country.
