Sometimes it can be hard to think of what kinds of primary sources might be available for the topic you are interested in. Here are some strategies you can use to start your search.
You can use the library search system - OneSearch to find books with primary sources. This includes reprints of original works like letters, speeches, and diaries, as well as published works like autobiographies.
Use Keywords to search for common kinds of primary source materials
When searching in One Search, using the Advanced Search option to limit your results. Use the subject heading for primary sources and type in sources for your search.. A subject heading is like a #hashtag in social media. Each item is 'tagged' with what it is about and the tag allows users to search for things on that topic, or click on the tag to get more items like it.
The search shown below for Thomas Jefferson as author and a publication type limiter for primary source document would find inaugural addresses and letters. When searching for primary source documents, look also for document type limiters such as speech or interview.
