Many digital collections available online through open access digital repositories contain primary sources that are publicly available for free. Primary sources are also available through the library's subscription-based databases accessible via MyCoyote.
When searching for and using online primary sources it is important to evaluate the credibility of the source. A helpful guide on finding, evaluating, and using online primary sources can be found on the Reference and User Services Association's (RUSA) website, http://www.ala.org/rusa/sections/history/resources/primarysources.
