What tsundoku actually is, and what to do about your pile

Tsundoku is the Japanese term for buying books faster than you can read them, first recorded in print as early as 1879. If your shelf has a stack you keep meaning to get to, there's a word for it, it's older than you'd think, and BookTok has made it considerably worse.

What does tsundoku actually mean?

The word combines tsumu, to pile up, and doku, reading. In Japan it carries no real stigma. It's a neutral, even fond, description of a book lover's shelf rather than a character flaw, closer to calling someone well-read than calling them a hoarder, and it's been in use for well over a century, long before anyone had a TBR list saved on their phone.

Why is BookTok making tsundoku worse?

Buying rate has outpaced reading rate for a lot of readers over the last few years, and BookTok is the main reason why. A book gets fifteen seconds of hype and a one-tap link to buy it, which is a much smaller ask than the discipline it takes to finish what's already sitting on the shelf. Nearly a quarter of UK book buyers say BookTok has directly driven a purchase, and titles tagged with BookTok keywords have sold in the millions of copies within months of going viral. Secondhand shoppers now name books as the single item they buy preloved most often, ahead of clothes and everything else people typically resell. The result is a generation of readers buying faster than they could ever realistically keep up with, one trending release at a time.

Is an unread pile actually a bad thing?

Not necessarily. The writer Umberto Eco kept a library of roughly 30,000 books and had read only a fraction of them, arguing that the unread portion mattered more than the read one, since it represented everything still left to explore. An unread shelf can be a reading plan as much as a guilty conscience. The problem isn't owning more books than you've read, it's owning books you'll genuinely never get to while still paying full price for the next one anyway, which is where the pile stops being aspirational and starts being an expensive habit that just keeps growing.

What should you actually do with unread books?

Donating clears the shelf but gets you nothing back. Selling means listing an item, waiting for a buyer, and usually spending the cash on more books, which is exactly how the pile got this big in the first place. Swapping is the only option that closes the loop properly. The book you were never going to read goes to someone who genuinely wants it, and you come away with something you actually will read, no cash changing hands, no waiting on a buyer, and no guilt sitting on the shelf in the meantime. That's the whole idea behind swapping rather than just buying or selling.
