How many sources does a research paper need?

It depends on length and level, but quality matters more than quantity. Use enough credible sources to support every major claim — your instructor's guidelines are the rule.

What's the difference between an essay and a research paper?

A research paper relies more heavily on external sources and formal citation, and usually involves deeper investigation, but both present a structured argument.

How to Write a Research Paper

A research paper is an extended, evidence-based argument. Break it into stages and a daunting assignment becomes a manageable project.

Step 1: Choose and narrow your topic

Pick a topic that is specific enough to cover well but broad enough to find sources. Turn it into a focused research question — the narrower, the better.

Step 2: Find credible sources

Use your library databases, Google Scholar, and .edu/.gov sources. Evaluate each source for authority, accuracy, and bias. Keep a running record of every source for your bibliography — see how to cite sources.

Step 3: Build a thesis and outline

Your thesis states the argument your evidence supports. Outline your sections so each builds the case logically.

Step 4: Draft

Write the body first, then the introduction and conclusion. Integrate evidence with your own analysis — never just stack quotations. Every claim needs support and a citation.

Step 5: Cite and revise

Apply your required citation style consistently, then revise for argument, clarity, and flow before proofreading. Citing accurately is essential to avoid plagiarism and to give credit to your sources.
