Common mistakes
- Mixing bibliography formatting with in-text citation rules. Reference-list entries and in-text cites follow different patterns — use the style's official guide for both.
- Forgetting the DOI. When a DOI exists, most styles now require it (usually as a full https://doi.org/… URL).
- Inconsistent capitalization. APA uses sentence case for titles; MLA and Chicago use title case. Mixing them is the single most common style error.
