If you would like to work with primary source materials in the original, consider using Smith's Sophia Smith Collection. A topical list of their major collections is available on their Collections by Subject page. Note in particular their collections on Women of Color and Race Relations in the U.S..
Materials relating to the history of the college are housed in the College Archives. Letters, diaries, and other primary sources documenting student life at Smith are listed on the Research Guides page. You might also wish to explore the records of specific academic departments or committees relating to curricular matters.
Consult with the collection curators for other ideas.
In short, primary sources serve as the raw material to interpret the past, and when they are used along with previous interpretations by historians, they provide the resources necessary for historical research.
