Most self-published authors think of book distribution as one thing. Upload to Amazon, the book is distributed. That picture is incomplete. Book distribution is actually a network of channels, each with its own economics, requirements, and reach. Amazon is one channel. Apple Books is another. Library systems form another. Brick-and-mortar bookstores form yet another. Each channel reaches different readers, pays different royalties, and requires different setup work. Authors who learn the full distribution picture tend to earn more than authors who default to single-channel strategies.
This post walks through how book distribution actually works in 2026, what the main channels are, and how to make smart decisions about which ones to use.
What Distribution Actually Does
Book distribution is the system by which books move from publisher (or self-publisher) to the readers who buy them. Several things have to happen for that movement to work.
Books need to be available in retail catalogs that buyers and consumers can search. Retailers need a way to order copies (digitally or physically) when buyers want them. Money needs to flow from buyers back through retailers and distributors to authors and publishers. Inventory needs to be managed so retailers don’t run out or sit on dead stock.
For digital books (ebooks and audiobooks), distribution is mostly a matter of being listed on retailer platforms. The “inventory” is digital and unlimited. The complexity is in being on the right platforms with proper metadata and royalty arrangements.
For print books, distribution includes physical inventory management, returns, shipping, and warehousing. Print-on-demand has changed this significantly by eliminating inventory risk, but the underlying complexity remains.
For audiobooks, distribution combines digital delivery with subscription and credit-based purchasing systems that don’t exist in print or ebook.
Direct Retailer Distribution
The most straightforward distribution path is uploading directly to each retailer’s self-publishing platform.
Amazon KDP. Direct distribution to Amazon Kindle Store, Amazon paperback, hardcover, and through Audible/ACX for audiobooks. Reaches the largest single book market by far. Royalty rates of 35% to 70% depending on price tier.
Apple Books. Direct distribution to Apple’s ebook and audiobook stores. Smaller market than Amazon but loyal users. 70% royalty on ebooks.
Barnes & Noble Press. Direct distribution to B&N’s NOOK ebook store and B&N’s online print catalog. Smaller market but real distribution. 40% to 65% royalty depending on price.
Kobo Writing Life. Direct distribution to Kobo’s ebook and audiobook platforms. Strong international reach, especially in Canada, Netherlands, Japan, and other markets where Kobo dominates over Amazon. 70% royalty on ebooks.
Google Play Books. Direct distribution to Google’s ebook platform. Smaller in many regions but growing. 70% royalty.
Direct distribution requires separate account setup and file uploads for each retailer. The work isn’t difficult but does take time. Most authors find that direct distribution is worth it for the major platforms where they earn significant income.
Aggregator Distribution
Aggregators are middlemen who handle distribution to multiple retailers from a single upload.
Draft2Digital. The largest self-publishing aggregator. Distributes to Apple Books, Barnes & Noble, Kobo, Google Play, Tolino (European), Scribd, library platforms, and others. Takes a 10% cut of royalties before passing remainder to authors.
Smashwords (now part of Draft2Digital). Similar functionality with some historical platform-specific features.
PublishDrive. Aggregator with focus on library and educational distribution. Subscription model rather than commission.
StreetLib. International-focused aggregator with reach into markets that other aggregators don’t cover well.
The trade-off with aggregators is convenience versus revenue. Aggregators save you the work of managing multiple platform accounts. They take a cut for that convenience. For most authors, going direct to the top 2 to 4 platforms and using aggregators for everything else produces the best balance.
Some authors use aggregators for all non-Amazon distribution, keeping Amazon direct (where royalties are highest) and letting aggregators handle the rest. This single-aggregator-plus-Amazon approach reduces management overhead while maintaining decent earnings.
Print Distribution Networks
Print book distribution works through specific networks that connect publishers with retailers and libraries.
KDP Print. Amazon’s print-on-demand for paperback and hardcover. Books available on Amazon and through Amazon’s logistics network. Doesn’t reach non-Amazon retailers in any meaningful way.
IngramSpark. The largest print-on-demand network for indie publishers reaching non-Amazon retail. Books distributed through Ingram’s catalog get to thousands of bookstores, libraries, and online retailers worldwide. The standard for wide print distribution.
Lightning Source. Ingram’s professional-grade print service, similar to IngramSpark but with higher minimum orders and different pricing structure. Used by smaller publishers rather than individual authors typically.
BookBaby Print. Print-on-demand with broad distribution. Higher costs than IngramSpark but with package services that include some distribution work.
For broad print distribution, most authors use both KDP Print (for Amazon) and IngramSpark (for everything else). This combination reaches Amazon plus the rest of retail through a single non-Amazon channel.
IngramSpark also handles wholesale relationships. Bookstores ordering through Ingram can stock or special order self-published books. The reach is real but actual store stocking is rare unless the book has demonstrated sales momentum.
Library Distribution
Library distribution is its own channel with specific platforms and economics.
OverDrive. The largest library ebook and audiobook platform. Reaches public libraries throughout North America and many international library systems. Direct distribution to OverDrive requires application and approval.
Hoopla. Streaming-style library platform for ebooks, audiobooks, and other content. Different economics from OverDrive (per-borrow pricing rather than purchased copies).
Bibliotheca CloudLibrary. Another major library platform with similar reach to OverDrive in certain regions.
Findaway Voices (for audiobooks). Distributes audiobooks to library platforms in addition to retail. Often the easiest path for self-published audiobooks to reach library systems.
Library distribution doesn’t usually produce immediate income comparable to retail sales. But library copies expose books to readers who might not buy directly, and library borrowers often become buyers of an author’s other books. The long-term audience-building value matters even when short-term income is modest.
Direct library distribution requires applications and approvals that aren’t always granted to individual self-publishers. Aggregators like Draft2Digital and PublishDrive often handle library distribution as part of their services.
Direct Sales Channels
Beyond retailer and library distribution, some authors sell books directly to readers.
Author websites with ecommerce. Selling ebooks, signed paperbacks, or other direct products through your own website. Higher per-sale revenue (no retailer cut) but requires technical setup and fulfillment management.
Shopify and similar platforms. Standardized ecommerce solutions for selling direct. Tools like Bookfunnel can handle ebook delivery to buyers after they purchase through Shopify.
Patreon and Substack. Subscription-based direct sales for ongoing content. Authors who can deliver regular content can build recurring direct income that rivals or exceeds royalty income.
Crowdfunding. Kickstarter, Backerkit, and similar platforms for funding specific book projects in advance. Premium tiers can include signed copies, exclusive editions, or other extras that justify higher prices than retail.
Direct sales work best for authors with established audiences who already trust them. Trying to drive direct sales from cold traffic usually fails because the friction is higher than buying through familiar retailers.
The math for direct sales is more involved than retailer sales. You pay payment processing fees, ecommerce platform fees, fulfillment costs, and ongoing maintenance. But the net margin can still beat retailer royalty rates when volume justifies the setup.
International Distribution
International distribution requires its own decisions and setup work.
Amazon distributes globally through their international stores (Amazon.de, Amazon.co.jp, Amazon.com.au, etc.). KDP handles the global rollout from a single upload. Royalties get paid based on each marketplace’s tier structure.
Aggregators like Draft2Digital extend international reach through their network. Apple Books, Kobo, Google Play all distribute internationally, often into markets where Amazon’s presence is weaker.
For markets like Japan, China, India, and parts of Europe, specialized aggregators reach platforms that Western aggregators miss. StreetLib particularly serves these markets.
Print distribution internationally is more limited. IngramSpark prints in the US, UK, and Australia, with shipping to other markets. The shipping costs and delivery times make international print sales less attractive than ebook or audiobook international sales.
Language matters significantly. Books in English reach a global market through retailers. Books in other languages need translation, separate ISBNs, and often separate distribution arrangements for each language version.
Distribution Economics
Different channels pay different royalty rates with different deduction structures.
Direct retailer distribution typically pays the highest royalties to authors. Amazon’s 70% tier and Apple’s 70% rate represent the high end of self-publishing royalties.
Aggregator distribution pays slightly less due to the aggregator’s commission. A book earning 70% royalty through Apple direct might earn roughly 63% through Draft2Digital after their 10% commission.
Library distribution often uses different economic structures. Per-borrow payments rather than per-purchase royalties. OverDrive payments per copy might be lower than retail royalties but the volume can compensate over time.
Direct sales can pay much higher percentages but require infrastructure costs. A book sold direct might net 80% to 90% after payment processing, but only after ecommerce platform and fulfillment costs are accounted for.
Print royalties are typically much lower than ebook royalties due to print costs. A paperback at $14.99 might generate $3 to $5 in author royalty after print and platform costs, compared to an ebook at $4.99 generating $3.49 in royalty.
Choosing Your Distribution Mix
The right distribution mix depends on several factors specific to your situation.
For new authors testing the market. Start with Amazon KDP. Single platform, lowest setup complexity, largest market. Add other channels after Amazon is working.
For wide distribution. Direct to Amazon, Apple, Kobo, and Barnes & Noble. Aggregator for everything else. This combination reaches roughly 95% of the self-publishing-accessible market.
For authors prioritizing Kindle Unlimited. Amazon KDP exclusively through KDP Select. No other channels. The KU income on a successful book often exceeds total wide income, but with single-platform risk.
For authors with significant direct audience. Heavy emphasis on direct sales through their own website and platforms. Retail distribution as supplementary income. Highest margins but requires ongoing audience-building work.
For nonfiction authors with corporate or institutional buyers. Add IngramSpark for library and institutional sales. Some markets require traditional distribution channels that aren’t available through Amazon alone.
Common Distribution Mistakes
A few patterns regularly cost authors money in distribution decisions.
Default to single platform without considering alternatives. Authors who upload to Amazon and ignore other channels miss significant revenue.
Wide distribution without committing to it. Authors who upload to other platforms but don’t market for them see minimal results. Each channel needs at least basic attention to produce sales.
Skipping IngramSpark for print. Print-only on KDP misses non-Amazon retail entirely. The setup investment in IngramSpark pays back across years of sales.
Inconsistent metadata across platforms. Different descriptions, different keywords, different prices across platforms confuse the discovery algorithms and undermine each platform’s reach.
Not reading terms before signing. KDP Select exclusivity, aggregator commission structures, and platform-specific clauses all have implications. Read carefully before committing.
Book distribution explained at the level that matters covers more channels and decisions than most authors initially consider. The right distribution mix depends on your goals, your audience, and the specific characteristics of your books. Authors who learn the channels and make conscious choices tend to outearn authors who default to single-channel approaches. The work to learn distribution properly is one-time learning that produces revenue benefits across every book published for the rest of your career.
A final thought on distribution timing. Most authors should expect 12 to 24 months before the full benefits of wide distribution show up in their income statements. Library platforms take time to acquire copies. International markets take time to discover authors. Aggregator channels take time to flow significant traffic. The patience required for wide distribution sometimes discourages new authors who see Amazon producing immediate income while other channels stay quiet. Stick with it. The cumulative income from wide distribution typically catches up to and exceeds the convenience of single-platform thinking by year three or four of a serious publishing career.
