Finding Primary Sources
There are many types of primary sources, including manuscripts, diaries, court cases, maps, data sets, experiment results, news stories, polls or original research. Here you'll find suggestions for locating these at the Northwestern Libraries.
Define your parameters
You can narrow your search by:
- Discipline (e.g. art, history, physics, political science)
- Format (e.g. book, manuscript, map, photograph)
- Type of information you need (e.g. numerical data, images, polls, government reports, letters)
- Date range
Use search tools
The NUsearch advanced search option can locate some primary source material in our collection. With "Subject" selected from the dropdown- menu enter the format, information type or date range (such as "Roosevelt Eleanor 1884-1962 Diaries" or "Chicago Ill Maps") into the search box.
