The reference page goes
at the end of your paper, after the main body of your text and any appendices. It should be on a separate page and formatted according to the specific style guide you are using (e.g., APA, MLA, Chicago).
Here's a typical paper structure:
1. Title page
2. Abstract (optional)
3. Introduction
4. Body paragraphs
5. Conclusion
6. References
7. Appendices (optional)
