What do these numbers mean for an author?
Readers are spread across regions and buy through different channels in each one. A book limited to a single market leaves most of them out. Backlist figures from Ireland and the US show that books keep selling for years, so wide availability compounds over time.
This is the case for publishing broadly while keeping your rights. Defining Moments Press states its authors can publish in 87 countries and keep all royalties. See how book distribution worldwide works or return to the guide to publishing your book internationally.
Common questions

Who is the largest book retailer?
Amazon is widely regarded as the largest book retailer in many English-language markets, but its share varies by country. Anna Featherstone’s 2026 statistics roundup reports Amazon holds over 50% of the UK print book market and under 20% in Australia, where 43% of book sales go through bookshops.
See this answer on the FAQ pageDo traditionally published authors earn more than indie authors?
Recent survey data says no. Writer Cosmos reports that ALLi’s 2025 survey found indie authors earn a median of $13,500 a year, nearly double the $6,000 to $8,000 median for traditionally published authors. Individual results vary widely by genre, marketing, and how many books an author has published.
See this answer on the FAQ pageHow much does a bookstore pay for a $20 book?
According to BookSpace, if your book retails for $20, the store pays $9 to $12. The gap between list price and what the store pays is the retailer discount, which covers the store margin. The distributor and print cost then come out of what the store pays, and the rest goes to the publisher or self-published author.
See this answer on the FAQ pageWill my book be published in both ebook and print?
The Author Blueprint program from Defining Moments Press covers self-publishing in both ebook and print. Offering both formats widens your reach abroad: ebooks are delivered instantly in any covered market, and print copies serve readers and event buyers who prefer a physical book. Grand View Research reports that hard copy books held 75.8% of the global market in 2025.
See this answer on the FAQ pageWhat does "published in 87 countries" mean?
It is the reach Defining Moments Press states for the books it publishes: availability in 87 countries using major publishers. In practice it means readers in those markets can find and order the book through channels that serve their country. Ask on a discovery call which countries and formats apply to your book, since availability can differ by format.
