Mistakes to avoid
- Mixing formats — Never use APA and Vancouver in the same document
- Using outdated versions — APA 6 is no longer current; use APA 7
- Not verifying with your advisor — Even within the same university, different advisors may have preferences
We review APA 7, Vancouver, Chicago and IEEE against your program's current source. We do not assume one institutional format for an entire university. Quote your format review.
Which to choose if you have freedom
- APA 7 is common in social sciences, education, psychology and business research
- Vancouver is common in health-science and biomedical publishing
- Chicago for history, arts or humanities (uncommon in Honduras)
