This map shows the location of printing presses in the Americas from 1535 to 1800 whose products appear in the joint catalog of The Brown University Library and The John Carter Brown Library. The dots are sized based on the number of materials held on the Brown Campus, which may give a rough visual estimate of each location's published output.

Note on visualization: Circles are drawn in descending order of size to ensure that larger publishing centers do not 'obliterate' smaller ones. However, the temporal aspect of this vizualization has no relation to chronological time.
This data set has known issues, but it is an attempt to show the range of publishing in North and South America. To see a cleaner, smaller data set, look at this map.
