Types of Resources
Primary sources are created at the time historical events occurred. Primary sources could also be made after historical events have taken place by someone who was there (for example, memoirs or oral histories). Some of the most common types of primary sources are letters, diaries, newspapers, statistics, interviews, memoirs, oral histories, speeches, or artifacts.
Secondary sources interpret or analyze an historical event. Most secondary sources are books with footnotes or endnotes, journal and magazine articles that analyze or interpret past events, biographies, book reviews, or literary criticism.
Keywords & Boolean Operators
Keywords are the words you put into a database's search box for results.
Keywords are important because databases simply look for articles where your keywords show up. You want enough keywords to find a relevant article, but not so many that the database gets confused.
To come up with keywords, write down your topic's big idea terms. Don't think about the question you want answered, think about the words that would show up in your ideal article. Then do a search in one of our databases, write down other words keep coming up, and add them to your list.
This is a trial and error process, so give yourself some time and don't give up!
Boolean Operators are words that you can use in between keywords to widen or narrow your search. They're easy to use and make a big difference! The most popular Boolean operators are:
Most databases have an "advanced search" option that allows you to make Boolean searches easier. Try it out!
