What is the difference between MLA and APA?
MLA (Modern Language Association) and APA (American Psychological Association) are two different sets of rules for formatting papers and citing sources. The main difference lies in what each discipline values most. MLA values the author and the specific page a quote came from, which makes sense for studying literature. APA values the author and the year the research was published, which makes sense for the fast-moving sciences.
Think of it like organizing your closet. If you organize by color, you are doing it because color is what matters most when you pick an outfit. If you organize by season, you care most about the weather. MLA organizes by "who wrote it" (authorship), and APA organizes by "when it was written" (currency of research).
Why the different rules exist
Different subjects need to highlight different information. In English or History (the humanities), a quote from a book written in 1920 might be just as relevant as one written yesterday. Therefore, MLA focuses on the author's name and the exact page number where the text can be found.
In Psychology, Biology, or Sociology (the sciences), research changes constantly. A study on memory from 1990 might be entirely outdated by a study from 2022. Because of this, APA format requires the publication year right next to the author's name in the text so the reader immediately knows how recent the information is.
How to recognize MLA vs APA
You can tell these styles apart by looking at a few key features. In MLA, your paper usually does not have a separate title page. Your name and class info go at the top left of the first page. The list of sources at the end is called "Works Cited."
In APA, you generally need a separate title page. The list of sources at the end is called "References." The way the sources are written also looks slightly different, especially concerning where the date is placed and how the author's first name is handled (MLA uses full first names; APA uses initials).
Where students slip up
The most common mistake is mixing the two styles together. A student might put a year in an MLA in-text citation, or forget the year in an APA citation.
Another frequent slip-up is the punctuation in the parentheses. MLA uses no commas between the author and page number, like (Smith 15). APA uses commas to separate the information, like (Smith, 2020, p. 15). Always double-check which set of rules your instructor requested before you finalize your citations.
Worked through
You are quoting a book written by John Doe, published in 2021. The quote is on page 42. How do you write the parenthetical in-text citation at the end of your sentence in both MLA and APA?
In MLA format, you only need the author's last name and the page number, with no comma in between: (Doe 42)
In APA format, you need the author's last name, the year of publication, and the page number, all separated by commas. You also use 'p.' for the page number: (Doe, 2021, p. 42)
