A wide variety of primary sources can be found outside the library, and many of these are freely available on the Web. The great majority of these are supported by libraries and museums around the world. For example, the Library of Congress has a service called Chronicling America (see below) that provides free scanned images of newspapers from all over the United States going back to 1789. There is almost no limit to the range of subjects with sources online, but the following are great places to get started looking for primary sources online.
