Here’s the thing that will save your bacon: pick one style (APA, MLA, Chicago) and stick to it like glue. If you use “&” in one citation and “and” in the next, you’ll confuse your reader. That’s like wearing one sneaker and one dress shoe to a wedding.
Your professor doesn’t care if you prefer “&” or “and.” They care that you do the same thing every time. Consistency is the secret sauce. It makes your paper look like a professional job, not a ransom note.
APA Citation Format Guide: Everything You Need (with Examples)
So when in doubt, look at your style guide’s example. It’s like looking at the picture on the box of a puzzle. It shows you exactly what the final product should look like. No guessing, no yoga for your brain.
What If You’re Writing a Book or a Song Title?
Don’t overcomplicate it. The citation stays exactly the same. The authors’ names go in the parentheses. The book title goes in your sentence. Imagine two chefs wrote a cookbook. You don’t put the recipe in the citation; you just say who made it.
For example: In their book, How to Survive Family Dinners, Klein and Foster (2026) suggest hiding vegetables in dessert. The citation just thanks the chefs. The book title gets to shine in the spotlight.
And please, don’t italicize the authors’ names. Only the book title gets that fancy treatment. You wouldn’t put a tuxedo on a pair of socks. Keep the authors in their regular clothes.
