My professor says a literature review is a primary source—should I treat it like a research article in my 2,500‑word ESL argumentative essay for a sociology class?

No, a literature review is not a primary source, and you should not treat it like a research article in your essay. Primary sources are original data or firsthand accounts, while a literature review is a secondary source that synthesizes existing research. Your professor likely misspoke or meant that the review itself is the primary component of your assignment, not that it constitutes primary evidence. Treating it as a primary source would lead to incorrect citations and a fundamental misunderstanding of academic hierarchy. Instead of summarizing each source individually, organize your review thematically to show how different sociologists debate your specific argument. For instance, if you’re discussing social media’s impact on community, group sources by themes like isolation versus connection rather than listing them chronologically. This creates a cohesive narrative that supports your thesis rather than just reporting facts. In MLA style, cite the literature review as a secondary source when referencing the ideas it synthesizes, but always trace back to the original authors for direct claims. This approach strengthens your argument flow by demonstrating critical engagement with the field, which is exactly what your instructor wants to see. Focus on synthesizing perspectives to build your own case, ensuring every paragraph advances your central claim rather than just describing what others have said.
