World Digital Library
Looking for primary documents? The World Digital Library can help. It contains manuscripts, maps, letters, rare books, recordings, film, photographs and architectural drawings from around the world and in different languages. You can browse their online collection by region, time period, topic, the type of institution that houses the item (like the Library of Congress or the Bibliotheca Alexandrina), or by the type of item. For example, here is a map of British Antarctic expeditions from 1907 to 1909 made by the famous explorer Sir Ernest Shackleton!
