Special Collections holds items related to twentieth-century wars that can be found through our website or the Libraries' catalog.
There are certain words that appear in the subject headings of items in library catalogs that designate primary sources. The most important of them is sources, but there are others.
In the simple keyword search box on the library homepage (Discover@MU), you can put such words, enclosed in "quotation marks," after SU in order to specify the SUBJECT field.
ex.: world war and France and SU "sources"
In the advanced keyword search of Discover@MU, or in any multi-line search interface, you can put your search term(s) in the top box, and in the second box, put the word(s) you're using to locate primary sources in the next box, and change the drop-down menu to SU Subject Terms.
