What Is Fair Use Copyright?
Fair use copyright is a part of U.S. copyright law that allows you to use small portions of copyrighted work without permission, especially in nonfiction books. It generally applies when you’re using the material for:
- Criticism or commentary
- Teaching or education
- Research and scholarship
- News reporting

Rule #1: Understand What Fair Use Copyright Really Means
Fair use copyright is part of U.S. copyright law that allows limited use of copyrighted materials without needing permission—only under specific conditions.
According to the U.S. Copyright Office, fair use may apply when the material is used for:
- Criticism or commentary
- Teaching or educational purposes
- News reporting
- Research and scholarship
That means if you’re quoting a brief line from a book to support your argument, or referencing someone’s theory while giving them credit, you’re likely operating within fair use.
But here’s the catch: there are no strict word limits. Instead, the law evaluates whether the amount used is reasonable and appropriate for the intended purpose.
Rule #2: Always Attribute—Even When It’s Not Legally Required
Here’s something many authors find surprising: U.S. copyright law does not require attribution under fair use. That means you can technically quote something without crediting the source.
But should you?
Absolutely not.
Attribution is about more than just legality. It’s about respect, credibility, and professional ethics. If another author quoted your words without credit, you’d likely feel cheated—and your readers might question your integrity.
So even though the law doesn’t mandate it, the smart move is always to cite your sources clearly.
This is especially critical when you’re navigating self-publishing copyright territory—because you’re the publisher, and the responsibility is all yours.
Rule #3: Only Use What Supports Your Argument — Not Just for “Flavor”
Many authors add quotes at the start of chapters or include pop culture references just to make the writing more entertaining. Unfortunately, this kind of usage often falls outside the protection of fair use copyright.
Here’s a helpful way to check:
- ✅ Fair Use: The material supports, illustrates, or expands on your point.
- ❌ Not Fair Use: You’re using it just because it’s entertaining or inspiring.
So, that powerful quote from Steve Jobs at the top of Chapter 3? It might not be covered unless it’s integral to your argument.
Instead of relying on borrowed inspiration, craft your own original content or find material that’s in the public domain or has a flexible license (like Creative Commons).

Rule #4: Don’t Copy Charts and Graphics—Create Your Own
Here’s a common self-publishing mistake: authors find a compelling graph or chart online and paste it directly into their book.
🚫 Bad idea.
While facts and data are not protected by copyright, the presentation of those facts is. That means charts, infographics, and even tables can be copyrighted due to their visual design and layout.
✅ What you can do:
- Recreate the chart using the same factual data—but in your own layout and style
- Reference the data source in your text and link or cite it properly
This is not just about staying legal—it’s about creating something original that adds unique value for your readers.

Rule #5: Know When Copyrights Expire (and Use Public Domain Wisely)
Sometimes, you don’t need to worry about fair use at all—because the material is in the public domain.
So, do copyrights expire? Yes, and when they do, anyone can use that material freely.
How long does copyright last?
- For works created after 1978, copyright lasts for the author’s lifetime plus 70 years
- Older works or government-produced content may already be public domain
Use the U.S. Copyright Office’s FAQ to check if something’s expired.
Using public domain content is a great strategy for nonfiction authors—especially when writing historical or educational material. Just make sure the version you’re using is truly public domain (not adapted or repackaged).
Pro Tip: Protect Your Own Work
While you’re being careful with other people’s content, don’t forget to secure your own. Registering your book’s copyright gives you:
- Legal protection
- Ownership proof
- Leverage in case of infringement
