Caribmap is a non-profit online library of historical and modern maps, including topographic maps, of the Caribbean islands. Since its establishment in 1999, the site has accumulated approximately 1800 maps of the islands that have been printed since the beginning of the 16th century The purpose of the site is to allow users, such as historians and scientists, to gain detailed information, including place names, from the high resolution map scans. For this, it uses a zoomable user interface (ZUI), Deep Zoom, so that the scale of the viewed area can be changed.
