When you use source material outside of your own experience, you’re using either primary or secondary sources. Primary sources are sources that were created or written during the time period in which they reference and can include things like diaries, letters, films, interviews, and even results from research studies. Secondary sources are sources that analyze primary sources in some way and include things like magazine and journal articles that analyze study results, literature, interviews, etc.
Sometimes, you’ll be conducting original research as you work to develop your argument, and your professor may encourage you to do things like conduct interviews or locate original documents. Personal interviews can be excellent sources that can help you build your ethos, pathos, and logos in your essay.
When conducting an interview for your research, it’s important to be prepared in order to make the most of your time with the person you are interviewing.
