What Is Nonfiction? Definition & Famous Examples

What is nonfiction, and why does it matter to know its definition?

Consider this: you want to write a book about your life, but you’re unsure if it will be listed as fiction or nonfiction. 

Why would a book about your life be fiction, you ask?

Well, while some authors prefer to base their stories strictly on reality, other writers choose to draw from true events while infusing the story with creative liberties. When people see a book listed as nonfiction, they assume that everything in it actually happened and is completely accurate – to the best of the author’s knowledge.

Conversely, when a book, movie, or series says “based on true events,” there is a lot of room for interpretations, exaggerations, and even completely made-up characters and parts of the story.

To get clear about this genre, I first ask (and answer) the question, what is nonfiction? Then, I explain how you can confirm a book is nonfiction, list popular subgenres and types of nonfiction books, share three classic characteristics of nonfiction books, and highlight a few famous nonfiction authors. So, are you ready?

First, what is nonfiction? 

A nonfiction book is one based on true events and as factually correct as possible. It presents true information, real events, or documented accounts of people, places, animals, concepts, or phenomena. There is no place for fictional characters or exaggerations in this genre.

But that doesn’t mean it won’t read like fiction. There are plenty of people who have such a fascinating or unbelievable story to tell that it doesn’t feel real. The Prince Harry memoir comes to mind. It has everything that you might find in a fantasy novel – except it really happened. A real-life prince? Yes. War, drama, and family conflict? Yes. A movie star wife? Also yes.

Others about trauma, death, and struggle have less magic to them, but could be equally difficult to believe due to the difficulties encountered by the author. An example here is the Jennette McCurdy memoir, I’m Glad My Mom Died.

There are plenty of other memoir examples, but memoirs are just one answer to, “What is nonfiction?” In reality, it includes a whole host of other subgenres.

How can I tell if a book is nonfiction?

For starters, any nonfiction book should be listed as nonfiction – whether online or in a physical book store. But if you want to be sure the book you have in your hands falls in this category, here’s what you can do:

• Examine the cover. Fiction books often have more artwork on the cover and may include a character or symbolism. Meanwhile, nonfiction book covers are often (though not always), more minimalist. Some may not have any artwork or may include a picture of the author.
• Find clues in the title and subtitle. Nonfiction book titles are often much more literal and descriptive about the subject matter. Exceptions to this are memoir titles, as they might be more interpretive.
• Read the author bio. A nonfiction author bio often leads with the author’s qualifications (a degree or lived experience) and reasons for writing the book, while a fiction author bio might be more personal or speak to other books the author has written.
• Look for a preface and/or table of contents. Most nonfiction books are penned to educate or help the reader. Many of them will have a preface introducing the concept or the author’s background on the subject matter. Similarly, they’ll likely include an easy-to-navigate table of contents, similar to a textbook or educational text.
• Scan the pages for citations or a reference list. Nonfiction books are factual. Therefore, the presented information should be backed up by studies, academic papers, or other reputable sources.
• Read reviews. This is much easier if the book is listed online. But nonfiction book reviews usually use words like “transformation,” “helpful information,” and “life-changing.”
• Consider the style and tone. While any author is free to use any tone in writing, most nonfiction authors default to an educational (even if casual) tone. Memoir authors may be the exception to this one, as most personal accounts are written in the distinct tone and voice of the author.

What types of nonfiction books are there?

When posed with the question, “What is nonfiction?” it’s also worth noting the different subgenres, types of writing, and themes in books that appear in the nonfiction category.

• Memoir and autobiography
• Self-help
• Business
• Spirituality or faith
• Health and fitness
• Cooking
• Art and photography

• Narrative nonfiction
• Creative nonfiction
• Essay
• Exposition
• Scientific works
• Historical accounts

3 purposes and characteristics of nonfiction 

Now you have a strong foundation and can confidently answer the question, “What is nonfiction?” Let’s go deeper. Why do people read nonfiction? What is the purpose of a nonfiction book?

Equally as important as being able to define nonfiction is to be able to describe the characteristics that make a book an effective nonfiction piece.

1. What is nonfiction? Inspiration.

One of the primary characteristics of nonfiction is its inspirational themes. While there are many types of nonfiction, most of them find a way to weave in enough inspiration to help readers want to better themselves and lead a better life.

Whether your book focuses on a personal victory – instilling in readers the idea that “I overcame this and so can you” – or uses data to inspire readers to join the 5 a.m. Club, nonfiction is inspiration, no matter how overt.

2. What is nonfiction? Education.

Educational nonfiction exists as its own sub-genre. However, even outside of strictly educational books, nonfiction includes lessons for readers who desire to self-educate.

Need an example? James Clear’s bestseller, Atomic Habits, stands as a key example of the power nonfiction has in educating readers – while inspiring change.

3. What is nonfiction? Self-discovery.

Some of the bestselling nonfiction today acts as a guide for readers intent on self-reflection. It often uses repetition in writing to portray a theme.

In fact, at a deeper level, answering the question, “What is nonfiction?” often comes down to identifying how a particular book helps readers see parts of themselves they would not otherwise see.

Let’s finish this long-winded answer to “What is nonfiction?” with some concrete – and a bit famous – examples. What better way to define what a nonfiction book is than to read some of the top books in the genre? Who knows, maybe you’ll learn something along the way!

Elizabeth Gilbert

Readers know Elizabeth Gilbert for her New York Times bestsellers Eat, Pray, Love and Big Magic.

Big Magic is a nonfiction book that focuses on creativity – and does so from a vulnerable perspective.
