Verdict
Use APA for social sciences, psychology, education, and business papers. Use MLA for literature, language, arts, and humanities. When in doubt, ask your instructor or check the journal's submission guidelines — there is no universal 'best' style, only the correct style for your context.
Why Different Disciplines Use Different Citation Styles
Citation styles encode the priorities and values of their disciplines. APA places the year immediately after the author's name because in psychology and social sciences, research builds rapidly and recency matters — a 2010 study on social media behavior is outdated compared to 2024 research. The prominent year tells readers instantly how current the evidence is. MLA places the page number instead of year because in literary studies, what matters is where in the text an author's argument appears. A scholar citing Shakespeare doesn't need publication year — they need Act, scene, and line. Each style reflects what readers in that discipline need to evaluate and locate sources efficiently.
Citation Tools and Workflow
Managing citations manually is error-prone and time-consuming. Modern citation managers (Zotero, Mendeley, EndNote) automatically format references in any style, sync across devices, and integrate with Word and Google Docs. Zotero is free and open-source, making it the best default for students. When writing in Google Docs, the built-in citation tool (under Tools > Citations) supports MLA, APA, and Chicago without third-party software. For occasional citation needs, MyBib.com and Citation Machine generate formatted citations without account creation. The key workflow: collect sources as you research (with Zotero's browser extension), then let the tool format your bibliography automatically.
Frequently Asked Questions
Most US high school English classes use MLA by default. Science classes may use APA or a simplified version. Always follow your teacher's or institution's specified style — the 'right' style is whatever your instructor requires, not an objective standard.
APA 7th edition (2020) eliminated the running head for student papers, changed how DOIs are formatted, added new source types for social media and podcasts, allowed up to 20 authors before using ellipsis, and changed paper formatting requirements. Most instructors now require APA 7, not APA 6.
Yes, citation generators like Zotero, Mendeley, Cite This For Me, and EasyBib can generate APA and MLA citations. However, always verify generated citations against the official style guide — generators occasionally have errors. Grammarly and Google Docs also include citation generation features.
