In the latest SHuSH newsletter, Ken Whyte considers the size of the North American book market at most recent count:

I’m often asked by writers about the prospects of a particular book. I try to be encouraging. If it’s a good book, there’s undoubtedly an audience for it. At the same time, I try to be realistic. It’s a crowded market and it’s often difficult even for a good book to find its audience.
If asked to explain just how crowded the market for books is today, I usually say something like, there are about two million books published in North America every year. I’m not sure where I got that figure from. Probably from some research I read five years ago.
Turns out it’s wrong. “The total number of books published in the US in 2025 with ISBN numbers jumped 32.5% over 2024 to more than four million books,” announced Publishers Weekly on March 17.
I can’t get over that number. Four million books.
An average reader might get through about 2,000 books in a lifetime. A long-lived super-reader churning through 70 or 80 a year may exceed 5,000. Gladstone’s reading logs suggest that he engaged with more than 20,000 books, but it’s not clear he read them all.
A large independent bookstore might carry between 10,000 and 30,000 books. A suburban chain store, 60,000 to 120,000. The Barnes & flagship at Union Square in Manhattan has hundreds of thousands of books on four massive floors. Powell’s City of Books in Portland, occupying an entire city block—you need a map to get from room to room—has at least a half million books, and by some counts a million. New York’s The Strand, which boasts 18 miles of books, new and used, is probably the world’s biggest bricks-and-mortar retailer: it has 2.5 million books on incredibly dense shelving. You’d need a Powell’s, a Strand, and a couple of B&N Union Squares to hold four million titles.
Four million books is equivalent in volume to the holdings of a good-sized university library system, or a large public library system—collections built over a century. And these are published in a single year.
In 1939, the year Margaret Atwood was born, The Library of Congress, widely recognized as the largest library in the world, home to a civilization’s worth of books, boasted about six million titles, including pamphlets. It’s now holding about 25 million, and the US alone is on pace to produce that many titles between now and the end of the decade.
Four million books. That’s 11,000 books a day. Four hundred and fifty books an hour.
A year ago, there were “only” 3.15 million books, traditional and self-published, released. So 2025 represents an increase of 32.5 percent. Self-publishing was up just under 39 percent. Traditional publishing about 6.6 percent. Publishers Weekly doesn’t offer much of an explanation for the explosion of new titles. AI has to be a major factor (see this week’s publishing sensation in The New York Times.)
Of course, most of the four million books are not worth your time. Only 642,242 of the titles were released by traditional publishers. A traditional publisher doesn’t guarantee quality, but it suggests a minimum of vetting. The search for merit among self-published books is easily frustrated.
Bowker, the service that counts the ISBNs (the unique thirteen-digit identifiers attached to each book), does not distinguish among formats. Many of the four million were published only as ebooks. And some books published as print, ebook, and audiobook are triple-counted. There may only be about 2.5 million distinct works in that total.
If one were to take the colouring books, planners, puzzle books, and AI-generated garbage out of the equation, we might be down to 1.5 million meaningfully distinct books. And of all those, maybe 1 to 3 percent, or 20,000 to 50,000, will sell over 1,000 copies. That puts some perspective on the four million.
