The Nonfiction Revolution: Authors Seize Control

Updated Oct 2026: this editorial has been rewritten and now cites its sources.

Nonfiction has long taken a distinctive path into print. Unlike most novels, a nonfiction book is often sold to a publisher before it has been written, on the strength of a proposal. That model still dominates traditional publishing. Alongside it, the data now show an enormous expansion in books that authors publish themselves, including large volumes of nonfiction. This editorial examines what the numbers say about that shift, and what it means for nonfiction authors deciding which route to take.

The traditional route

Jane Friedman, a longtime publishing industry analyst, explains in her guide to book proposals that in nonfiction a publisher convinced by a proposal "will contract you and pay you to write the book," and that this applies to all types of nonfiction. She notes that proposals typically run about 10 to 25 double-spaced pages, not counting sample chapters, and that they can take weeks or longer to prepare.

The model carries an important exception. Friedman writes that it can be very challenging for memoirists to sell a project on a proposal if they are unpublished or lack a compelling platform, and that unpublished or beginning writers might find it easier to write the book first.

The traditional market for adult nonfiction remains large. The Association of American Publishers' StatShot Annual report for 2025, released on 10 August 2026, estimated adult nonfiction revenue at $6.0 billion, up 1.3% from 2024, within total trade revenue of $21.7 billion. In the AAP's separate StatShot figures, which are based on results reported by 1,324 publishers, however, Publishers Weekly reported that adult nonfiction sales fell 2.5% in 2025, with digital audiobook sales down 5.9% and ebook sales down 2% in the category, while hardcover sales rose 2%. The two figures measure different things, one an industry-wide estimate and the other a reported sample, and together they suggest a mature market that is roughly flat rather than growing quickly.

The self-published surge

The more dramatic change has come in volume. According to Bowker figures reported by Publishers Weekly, the number of self-published print and ebooks with ISBNs rose 38.7% in 2025 to more than 3.5 million, from about 2.5 million in 2024. Traditionally published releases rose 6.6% to 642,242, from 602,428 in 2024. The 2025 jump was a rebound: self-published output had fallen in 2024 from its 2023 level of more than 2.6 million. Over the period from 2022 to 2025, traditionally published output grew 10% while self-published output grew 43.5%.

Nonfiction categories feature prominently in that growth. Among self-published titles in 2025, the top five genres were fiction (477,104 books), juvenile nonfiction (401,716), games and activities, juvenile fiction and travel. Bowker's Andrew Kovacs said those categories, together with self-help, accounted for over half of the increase in output. On the traditional side, business and economics and religion ranked among the top five categories.

Kovacs attributed the rise in part to new tools. "The fact that every aspect of the publishing process once available only through traditional publishers can now be obtained from the self-publishing service providers at a comparable level of quality" was likely the key driver, he told PW. He also noted that publishing the same title in several formats, each of which requires its own ISBN, adds to the count.

Control and its trade-offs

Advocates of self-publishing frame the change in terms of control. In an earlier PW report, Smashwords founder Mark Coker said self-published authors benefit from greater control over "pricing, promotion, and distribution," which lets them connect with readers "faster, and more profitably." The same report noted that Amazon said KDP authors had earned more than $3.5 billion in Kindle Unlimited royalties over the program's first ten years.

The income data lend that claim some support. The Authors Guild's 2023 author income survey found that full-time self-published authors had a median book income of $12,800 in 2022, and that those publishing since at least 2018 reported a median of $24,000, up 76% from $13,700 in 2018.

Control brings costs that a traditional publisher would otherwise cover. On Amazon's KDP, for example, the author sets the price and earns a royalty of 50% or 60% on print books minus printing costs, while costs such as editing and design fall to the author. And output is not the same thing as sales. PW observed that how much of self-publishing's growing output translates into sales is hard to determine.

Choosing a route

For nonfiction authors, the evidence supports a practical framework rather than a single answer:

• Authors with a platform and a strong proposal can still sell a book before writing it, with an advance and a publisher's support, as Friedman describes.
• Authors without a platform, memoirists in particular, may need to write the book first, which makes self-publishing a realistic option to weigh.
• Specialist and practical subjects, such as self-help, travel and activity books, are among the categories that account for much of the growth in self-published output.
• Volume cuts both ways. More than 3.5 million self-published titles in a single year means more competition for readers' attention.

A shift in who decides

The data do not show traditional nonfiction publishing collapsing; the AAP estimates the market at $6.0 billion. What they show is that a fast-growing share of new books, nonfiction included, now reaches the market without a publisher's decision. For authors, that widens the range of options. For readers, it makes the work of finding reliable nonfiction, books grounded in real expertise and evidence, more important than ever.
