3 Genius Public Domain Book Ideas for KDP You Can Publish for Profit (That Aren’t Just Reprints)

December 15, 2025 By Rachel Harrison-Sund

If you’re curious about public domain book ideas for KDP (and I’m guessing you are, since my last 2 public domain publishing videos have already racked up 145,000 views), I’m about to wow you again. 😂

If you need a reminder, public domain books are a wonderful opportunity because they are:

  • Already written
  • Copyright-free
  • Free for you to publish 

Which means they’re basically sitting there whispering, “Repurpose me…and turn me back into a bestseller again!”

Now, I’m not talking about simply dusting off an old classic, slapping on a new cover and calling it a day. (There is already an army of lazy so-and-sos doing just that.)

We’re going way more fun (and way more profitable) than that.

And that’s what I’m teaching in today’s brand-new video:

Inside, I show you three creative mashups where you take a beloved public domain classic and pair it with a currently trending low– or medium-content niche.

The kind of public domain book ideas for KDP that make you go, “Omg… how is nobody doing this?!”

Here’s what you’ll learn:

  • Why most people use public domain books wrong (and what to do instead)
  • 3 angles for transforming classics into brand-new, high-value products
  • How to elevate an existing work so buyers gladly pay for your enhanced version
  • The niche mashup that’s my personal favorite (don’t skip #3!)

Get ready to spark ideas and spot opportunities you’ve never noticed before.
