Frequently Asked Questions

What is the main difference between APA and MLA?
APA uses (Author, Year) in-text citations and is used in social sciences. MLA uses (Author Page) and is used in humanities. The reference list in APA is called 'References'; in MLA it is 'Works Cited'.
Which style is easier?
MLA is generally considered simpler for beginners because in-text citations only require the author's last name and a page number. APA has more detailed requirements for the reference list, including specific formatting for different source types.
Can I use APA and MLA in the same paper?
No. Choose one citation style and use it consistently throughout your paper. Check your assignment guidelines to confirm which style is required.
Do APA and MLA both require a title page?
APA (7th edition) requires a title page for most academic papers. MLA does not require a separate title page — instead, the identifying information appears at the top of the first page.
