Frequently asked questions
What is the main difference between APA and MLA style?
APA (American Psychological Association) emphasizes the publication year with parentheses right after the author for scientific recency. MLA (Modern Language Association) emphasizes authorship and page numbers for humanities.
How do in-text citations differ in APA vs MLA?
APA in-text citation uses author and year: (Smith, 2024, p. 45). MLA in-text citation uses author and page number: (Smith 45).
How do I cite a source with two authors in APA 7th?
Use an ampersand (&) in parentheses: (Smith & Jones, 2024), and in the reference list: Smith, J., & Jones, M. (2024).
What is a DOI in academic citations?
A Digital Object Identifier (DOI) is a permanent alphanumeric string providing a persistent link to scholarly journal articles online.

In APA 7th, standalone works (books, reports, web pages) have their titles italicized, whereas articles within journals have the journal name italicized instead.
