The Broer Map Collection includes historic maps and foreign language atlases from around the world along with road atlases from many eras. The maps range from the 16th through 20th century, with a focus on 19th and 20th century items. Maps can be searched by region, country, continent, or through the search engine. The site offers Google Earth so that certain historic maps can be compared from past to present. Images are offered in thumbnails that can be enlarged, with zoom, pan, and rotation features.
