What Is the Oxford Comma?
So what is this questionable Oxford comma? The Oxford comma is, you guessed it, a comma! It's placed in a series of three or more items before the coordinating conjunction. (You'll also see it called a series comma or a serial comma.) It can be used in both "and" and "or" lists as the last comma separating a series of items. It works to help order these items and provide a distinction between the items on the list, particularly the last two items. See several Oxford comma examples at play to understand the basics of how it works.

Who Invented the Oxford Comma?
The invention of the Oxford comma is debated almost as much as its usage. Why it's called the Oxford comma is easy to explain. Peter Sutcliffe used the term in his 1978 informal history of the Oxford University Press. The original invention is less clear. Sutcliffe credits the introduction of the Oxford comma to F. Howard Collins, who created the 1912 Authors’ & Printers’ Dictionary. Collins, in turn, cites philosopher Herbert Spencer as the authority.
When Is the Oxford Comma Needed?

How an Oxford Comma Can Change Meaning: Real-Life Cases
Worse than people thinking you're a liar and cheat, a lack of an Oxford comma can even have legal ramifications. Check out these real cases where the Oxford comma made a big difference.
Maine Delivery Drivers Lawsuit
A group of dairy delivery drivers in Maine received a $5 million settlement, due entirely to the lack of an Oxford comma. In legislative documents, certain tasks were singled out as exempt from overtime payments. The documents indicated that the "canning, processing, preserving, freezing, drying, marketing, storing, packing for shipment or distribution of" certain product are exempt from overtime payments.
Without a final comma in the series of tasks, "packing for shipment or distribution" could be read as "packing for shipment OR packing for distribution," where "packing for" is used for both "shipment" and "distribution." This is quite different from [packing for shipment] or [distribution], wherein the drivers are doing the latter task. By placing an Oxford comma before "or distribution," it would've been clear that "distribution" was its own separate act. Don't you think five million dollars is quite a loss, due the lack of a single, tiny comma? You can be sure an Oxford comma was added to the revised documents.

Obama's Surprise Engagement
When writing a tweet, you might not think about grammar, but it can lead to confusion. News sites, for example, might want to consider how things look when the Oxford comma is missing. In one tweet, SkyNews caused a bit of confusion on Twitter when they announced, "World leaders at Mandela tribute, Obama-Castro handshake and same-sex marriage date set ..." Without the Oxford comma, it's hard to tell whether Obama and Castro just shook hands or they are also planning a same-sex marriage!

What Style Guides Say About the Oxford Comma
Let's review the main style guides and see where each of the heavy-hitters comes down on the subject.
AP Stylebook
In September 2017, the Associated Press (AP) released a clear, concise statement via Twitter. They wrote, "We don't ban Oxford commas! We say: If omitting a comma could lead to confusion or misinterpretation, then use the comma." That's precisely the kind of thing that could've saved the state of Maine a whopping $5 million.
APA Stylebook
The APA Stylebook by the American Psychological Association, however, is far firmer on its stance on the Oxford comma. In the punctuation section of the guidebook, it states the APA "requires the use of the serial (or Oxford) comma in lists of three or more items."

The Chicago Manual of Style
Turns out the Chicago Manual of Style falls on the same side as the APA. It, too, requires the serial comma in a list of three or more items. It comes down to be a matter of ambiguity. In an effort to minimize exactly that, the Chicago Manual of Style calls for the serial comma.
MLA Style Guide
Finally, the MLA Style Guide from the Modern Language Association requires the use of the Oxford comma as well. The only style guide that leaves it open to interpretation is the Associated Press.
Oxford Comma: A Hot Debate
