Series 3, Professional Life, consists of materials produced by Vincent across her scholarly career from the 1960s to the 2010s as a professor and a researcher of anthropology. Processing archivists divided this series into four subseries. Subseries 3.1, Teaching Materials, contains materials produced by Vincent between approximately 1967 and 1995. Included in this subseries are syllabi, lesson outlines, lecture notes, and exams that reflect Vincent's teaching as a doctoral candidate at Makerere University College in Kampala, Uganda, and as a professor of anthropology at Barnard College and the City University of New York (CUNY). Subseries 3.2, Articles, conference presentations, and other writings, spans the mid-1960s to the early 2010s. It comprises the majority of the series' materials and primarily consists of unpublished articles and drafts on various topics; notes for conferences, panel presentations, and talks; copies of Vincent's curriculum vitae; and book reviews. Major topics in Vincent's writings within this subseries include Irish studies, peasantry, issues of ethnicity and capitalism, anthropological theory, African politics, ethnography, and the history of Columbia University's Anthropology Department. A smaller portion of the records in this subseries include notes, annotated secondary sources, and personal reflections for an untitled autobiographical project. Subseries 3.3, General Notebooks, comprises Vincent's handwritten notebooks which include research and teaching notes, autobiographical reflections, and accounts of her daily activities. The exact date of some of these notebooks is unclear, but processing archivists have estimated that some notes date to the 1960s, while others were produced between 2005 and 2015. Lastly, subseries 3.4 consists of Vincent's professional correspondence between 1965 and 2012 with colleagues, research informants, and students.
