Maps can be found in a variety of places and serve a variety of purposes. For example, a physical map can show how the climate changes by region in a specific country, a political map can show which regions prefer certain candidates based on geographic boundaries, and a sociocultural map can show the range of specific linguistic features.
On this page, you will find various websites that can help you find maps and other geographic information. This page is US-centric, for more information about world maps, ask your librarian.
