For your project, you need to research and identify primary sources. When you're looking for primary sources, look for sources that shed light on the topic you've chosen. If you're investigating the relationship between the Space Race and the Cold War, for example, you'll want to look for primary sources that touch on that topic or add some information to that conversation. You might seek out reports on the shuttle programs, letters from people who worked on shuttle or missile projects, or images of the same.
The best place to look for primary sources can vary widely depending on the topic you're interested in and the sources you would like to use. We've selected a few of the library's databases below that include primary sources. Want more? Check out the longer list of primary source collections in the History research guide.
