For your research, you may want to consider interviewing your classmates or perhaps an expert.
In this way, you are creating the primary sources that reflect the different voices you want to represent in your research.
Interview subjects might include a politician advocating for free college, a college administrator, trustee (board member), an economics instructor familiar with college budgets, book authors, activists, students and others.
Tips:
For APA format, personal interviews are not included in your reference list because they do not provide recoverable data for whomever is reading your list. Cite them as in-text only, as "personal communication."
