A primary source is any record contemporary to an event or time period. Primary sources may be written, oral, visual or physical. They may be intentional (created for posterity) or unintentional. They may be religious writings, literary works, maps, record books, songbooks, artworks, and more.
There are certain words that appear in the subject headings of items in our library catalog, that are used for primary sources. The most important of them is sources, but there are others.
In the simple keyword search box, you can put such words after SU: in order to specify the SUBJECT field.
ex.: ancient and (medic* OR surg*) and SU "sources"
In the advanced keyword search, 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.
