The same geography can be found in practically every reader’s home: a coffee table where something arrived two months ago and hasn’t moved since, a shelf with books turned sideways to fit, and a nightstand with a teetering stack. The books serve as a sort of sedimentary record, capturing the passions of various seasons, friend recommendations, and impulsive purchases from a bookstore that was difficult to leave empty-handed. Many of them have never been opened. It’s unlikely that some of them will ever be. And for some reason, the purchases go on even though they are aware of this.
There is a term for it in Japanese. The nineteenth-century portmanteau “tsundoku” refers to the practice of acquiring books and allowing them to accumulate unread. It was created by book lovers, for book lovers, indicating that the habit has always been surrounded by a certain sympathetic self-awareness. There is no shame associated with the word. It is acknowledged. The intriguing aspect of this realization is that the discrepancy between purchasing and reading books is a recognized psychological pattern with some distinct and easily comprehensible causes rather than a personal shortcoming.
The intention-action gap, as psychologists sometimes refer to it, is the most direct. Before any actual reading has taken place, purchasing a book offers a genuine reward: the enjoyable anticipation of reading it, the feeling of having made progress toward becoming more knowledgeable, cultured, or just amused. With the purchase comes the dopamine. The work begins with the reading. The brain is not subtle about which of those two things it prefers for the majority of people at most times. The reward is obtained, the book is purchased, and the reading remains secure in the future so that it won’t let anyone down.
With his concept of the antilibrary, Nassim Nicholas Taleb provided this tendency with a more generous framing. In The Black Swan, he makes the case that having an enormous library of unread books is not a monument to procrastination but rather a tool for intellectual humility—a continual tangible reminder of how much is still unknown. Taleb pointed out that Umberto Eco had tens of thousands of books, and he was annoyed when people asked him how many of them he had actually read, as if the ones he hadn’t read were a sign of waste rather than intent. According to this perspective, the purpose of an antilibrary is to go beyond what you’ve already eaten. Read books to learn what you already know. Unread books reveal things you may learn in the future if you pursue your curiosity far enough.
Even though that framing could occasionally be used as a convenient justification, there is something subtly appealing about it. The majority of people who purchase their fifth unread book in a week might not be developing a well-curated epistemological framework. Beneath the habit, however, is a real version of the aspiration. Books can serve as a kind of silent autobiography of the person one is attempting to become. For example, a book about trauma therapy acquired during a challenging year, the history of the Ottoman Empire purchased during a time of intellectual ambition, or the collected essays of a writer whose work one hopes to eventually comprehend. Even if the reading doesn’t follow, the shelf is a record of intention, and intentions are not meaningless.
In certain situations, purchasing also serves as a visual counterbalance to screens. A physical book on a table is an example of a passive prompt because it doesn’t alert you, doesn’t update, and doesn’t use variable reward to compete for your attention. In a way that a digital to-be-read list never quite accomplishes, some readers have observed that the mere sight of unread books in their living area encourages them to pick up reading again. There is the book. The cost has already been covered. It won’t go away. For some people, that subtle pressure—which is easy to ignore but actually exists—works occasionally.
It’s difficult to ignore how, in recent years, purchasing books has also evolved into its own aesthetic. The TikTok reading community, BookTok, uses the visual language of unboxing videos to treat book hauls: stacks on beds, covers spread out for the camera, and the color and texture of spines as unique objects. Before they are read, the books are exquisite. The shelf is a piece of art. Although this isn’t completely new—people have set up bookcases for impact for as long as there have been bookshelves—the social aspect of it has grown, transforming ownership into a sort of public declaration distinct from the actual reading.
None of this completely eliminates the guilt. The book that was bought on a flight, cracked open for one chapter, and hasn’t been touched since March still has that particular tiny weight. However, guilt might not be the best way to describe it. The tsundoku shelf is not an unfinished to-do list.
