What is the Difference Between a Primary Source and a Secondary Source?

According to A Manual for Writers by Kate Turabian (University of Chicago Press, 7th ed., 2007), "Secondary sources are books and articles that analyze primary sources, usually written by and for other researchers. You use secondary sources for three purposes: 1. to inform and refine [your] thinking; 2. to find other points of view; 3. to find models for your own research and analysis.

"Primary sources are original works—diaries, letters, manuscripts, images, films, film scripts, recordings, musical scores, and ... data collected through observation and experiment."
