Parenthetical Citation for Two Authors

Parenthetical Citation for Two Authorsにまつわる役立つ知識を分かりやすく発信ます。

Here’s the simple trick: inside your parentheses, you write the last names of both authors, and you connect them with an ampersand (&) instead of the word “and.” Why the ampersand? Because it’s faster, like using a shortcut in a video game. “And” feels like a long walk; “&” feels like a teleport.

For example, let’s say you read a book by Smith and Jones. Your citation should look like this: (Smith & Jones, 2026). That’s it. Two names, one little squiggle, and a year. It’s the academic equivalent of holding up two fingers to order two coffees—efficient and clear.

The ampersand is not a fancy doodle. It’s a signal to your reader: “These two folks co-authored this, so don’t give all the credit to one of them.” It keeps the peace in the library.

When You Use “and” vs. “&”

Here’s where it gets a little weird, like when you’re supposed to use a fork for salad but a spoon for soup. In your in-text parentheses, always use the &. But if you’re writing the names into the actual sentence—like “Smith and Jones argue that…”—then you write out the word “and.”

Why? Because English is a beautiful, confusing mess. Imagine saying, “Smith & Jones argue…” out loud. It sounds like a law firm, not a research team. So in your own writing flow, be graceful: say “and.” Inside the parentheses, be speedy: use “&.”

I once forgot this rule in a paper about coffee addiction. I wrote, “(Anders & Klein, 2026)” in the sentence, and my professor circled it with a red pen that looked like a burning emoji. Learn from my shame.
