You read a self-published author's manuscript looking for anything a real editor's fact-checking department would have caught: a wrong century, a made-up chemical name, a river that flows the wrong way.
Every flag comes with a link to the source that proves it, because an author who self-publishes has no in-house team to argue with you, so the proof has to do the convincing. You work from a shared document and whatever library databases and archives you can get into online. The fee is set once you know the word count, before you start reading.

Indie authors spend months writing historical fiction, technical thrillers, or deep non-fiction, but a single reader review pointing out that daylight saving time didn't exist in can tank a book's ratings. Traditional publishing houses deploy dedicated copy desks for this, but self-published writers usually fly solo and hope for the best. Running a dedicated fact checking service for authors means combing through manuscripts line by line and verifying timeline details, period clothing, firearm specs, or regional geography against digitized archives and public library databases.
You charge a flat fee based on word count—typically around for a standard ,-word novel—delivering all corrections inside a shared document. Operating as a work from home manuscript research service works because you never just leave a comment saying a detail feels off; you link directly to the vintage municipal record or academic paper that proves it, which builds immediate credibility with the writer. Landing your first ten clients comes down to hanging out in online self-publishing communities, offering free ,-word sample checks, and showing writers real missteps you caught.
Position yourself as a specialized remote research assistant for writers who take accuracy seriously, and you will quickly build a list of repeat authors who refuse to publish without your final review. Growth hits a ceiling when your individual calendar fills up, meaning expansion eventually requires building a roster of freelance subject-matter specialists in areas like military history or medicine.

Self-published authors have exploded in number, and none of them have a publisher's fact-checking desk behind them. A wrong date or a botched piece of period detail is the kind of thing readers screenshot and mock in reviews, so authors who have been burned once become repeat clients. The market is small per author but steady, because everyone who self-publishes keeps writing more books.
Independent authors, mostly in historical fiction, thrillers with technical detail, or anything set somewhere they have never lived. They have either skipped fact-checking entirely, asked a friend to skim it, or trusted their own research and gotten unlucky. Most come to you after a bad review calls out an error, not before.
The fee is set once you know the manuscript's word count, agreed before you start reading. No royalties, no ongoing relationship unless they write a sequel.
Most editing services bundle fact-checking into a general line edit, so it gets a quick glance instead of real research. You do only this, and you show your work with a source link on every flag, which is what actually earns trust from an author who cannot check your work themselves.
This suits a former librarian, academic, or just someone who genuinely loves chasing down a fact until it is nailed down. If line-by-line verification sounds tedious rather than satisfying, or you want income that does not depend on your own reading hours, this is not for you.
Premium research
Basically nothing beyond your own time and a fast internet connection. You need access to library databases, many are free with a library card, and enough patience to chase down an obscure fact for as long as it takes.
Pay is small at first while you find authors willing to trust a stranger with their manuscript. It grows once a few authors recommend you in writing forums and groups, but it stays capped by how many pages you can carefully check in a week.
No sourced cost or earnings figures exist for this idea yet, so none are shown. Nothing here is an estimate.
Premium research
Pick a few genres you actually know well, such as history, science or a specific region, so your fact-checking has teeth.
Offer a free one-chapter sample audit to a few authors in a writing forum or group.
Set your per-word or per-page rate before you take a paid job, not after.
Deliver the first jobs with a source link on every single flag, even the small ones.
Ask happy authors to mention you in their acknowledgments or their writing community.
Keep a running list of your best sources by subject so the next book goes faster.
Months, not weeks. Authors do not hand an unpublished manuscript to a stranger easily. A visible sample, like a free one-chapter audit, speeds this up.
It depends on length and how research-heavy the book is. A tightly plotted contemporary novel might take a few days; a historical epic full of real events takes longer. Quote based on a sample chapter first.
You hand them the source and let them decide. Your job is to flag it clearly, not force a rewrite. Some authors take artistic license on purpose, and that is their call.
No, but you need to be genuinely good at research and comfortable saying you are not sure rather than guessing. A librarian, teacher, or obsessive hobbyist researcher can do this well without ever having worked in publishing.
