Primary sources are evidence that comes from the time period itself. In history, these are typically written or printed sources – letters, diaries, newspaper articles, advertisements, government records, etc. – but historians also draw on material objects, artifacts, oral traditions, oral interviews, music, and other materials.
Local archives in the area are one source of primary sources, which are usually related to community, regional or state histories. There is also a growing amount of primary sources that have been digitized and made available in their entirety on the internet. See the links below for collections with available primary sources.
