An antilibrary and the knowledge inside

On unread shelves, the weight of choosing, and the knowledge that lives in what you haven't opened yet

An antilibrary and the knowledge inside

That'sThis essay was rewritten in March 2025. You can find the original version at the end of this piece.

Nadia's apartment smelled like cardamom and old paper. The bookshelves covered three walls of her living room, floor to ceiling, and there was a system to them—I could tell by the way certain spines faced outward, and others were turned in, though I couldn't crack the logic. It was a Thursday evening, maybe 6:30, the kind of amber light that makes everything look like a memory even while it's still happening.

"How many have you read?" I asked, gesturing at the shelves with my coffee cup.
She didn't look up from the book she was reorganizing. "That's not the interesting question.”
"What is?”
"How many I haven’t.”

She said it without weight, the way someone mentions a country they've visited often enough that the name no longer carries romance. And something shifted in the room—not dramatically, but the way a lens adjusts when you turn the focus ring a quarter-turn. The shelves looked different. Not like a collection. Like something unfinished, deliberately.


I've been thinking about what Nadia meant, and I keep arriving at an idea that Nassim Taleb once articulated—the antilibrary. Not the books you've consumed and catalogued and can reference at dinner parties. The ones you haven't opened. The ones that sit there, accumulating, outnumbering the read ones year after year, their silence growing louder as you grow older.

I notice it during my own quiet confrontations with my shelves. A training hall has a similar architecture of humility—the longer you practice, the more techniques you discover that you execute poorly, that your body refuses to learn at the speed your mind demands. My instructors never shortened the warm-up, no matter how advanced the class was. "The basics don’t get smaller," and "You get more honest about them.”

An antilibrary works the same way. The unread books don't represent failure. They represent the territory you've been honest enough to map without pretending you've walked it. Each spine on Nadia's shelf was an admission: this matters, and I haven't arrived there yet. Not guilt. Something more like orientation.


Daniel runs a product team of twelve people. I had coffee with him on a rainy Wednesday, the espresso machine behind us doing that percussive thing where it sounds like it's solving a math problem. He'd just come back from a conference and was energized in that specific way people get when they've consumed a lot of ideas in a short time.

"I read six books last month," he said, and the number landed on the table between us with the confidence of a chess piece being placed.

I asked what he remembered from the third one.

The silence stretched. Three seconds. Five. Long enough for us both to notice.

"The general thesis," he said finally. "I could give you the thesis.”

Maybe the interesting thing about reading isn't the consumption. Maybe it's what happens in the choosing—the moment you pull one book from a shelf of two hundred and, in that gesture, say not yet to everything else. We treat reading as accumulation: books finished, pages turned, a counter that only goes up. But what if the more revealing metric is what you didn't pick? The books you circled and put back. The ones you bought for a version of yourself that hasn't arrived yet.

Daniel's six books were impressive in the way a filled passport is impressive—evidence of movement, but movement and understanding occupy different rooms. The antilibrary inverts the equation. It asks you to sit with the weight of the unchosen. Not because choosing is wrong, but because the unchosen books are still doing something. They're holding open a space that says: It's finished.

There's a particular quality of discomfort that lives in Nadia's shelves that I don't find in Daniel's reading list. Nadia's discomfort is generative. It creates an ongoing conversation between who she is and who she hasn't become yet. Daniel's six books, consumed and shelved, have gone quiet. They've answered their questions. The antilibrary keeps its questions open.

What I've noticed in my own stumbling relationship with this is that I keep wanting to resolve it. I'll look at my shelves and feel the pull to make a reading plan, to systematize the unread section, to create a framework of tags and categories that would let me pretend I'm managing the chaos. I've done this. More than once, I've spent a Sunday afternoon organizing books I haven't read into a taxonomy of intention—read next, read this quarter, read someday—as if sorting the spines would substitute for opening them.

It doesn't, of course. The organizing is its own species of avoidance—something that looks like engagement but is actually a way of standing outside the library while rearranging its furniture.

The antilibrary isn't a method. It's what remains when you stop pretending that awareness of knowledge is the same as possessing it. The shelves don't organize themselves into insight. They just stand there, honestly, reflecting back the distance between what you've touched and what you haven't.


I went back to Nadia's apartment a few weeks later. The light was different this time—later in the evening, the lamps on, the shelves casting long shadows that made the room feel deeper than its dimensions.

She'd moved some books. The ones that had been spine-out were now spine-in, and a new row of unfamiliar titles faced the room.

"Redecorating?" I asked.
"Rethinking." She pulled one out—something thick, with a cracked spine despite being unread, as if it had been waiting a long time. "I bought this four years ago. I wasn’t ready for it then. I might not be ready now.”
"So why pull it out?”

She turned it over in her hands, the way you'd examine something found at an excavation site—careful, curious, not quite committed to keeping it.

"Because I’m closer.”

I didn't ask what was closer. Some recognitions need to arrive on their own schedule, and the question would have flattened something that deserved its full dimension.

Outside, the city hummed its evening hum. Inside, the unread books kept their counsel, patient as sediment, waiting for the reader who hadn't quite arrived yet—but was, perhaps, one honest shelf-scan closer than before.


Original version (January 2024)

Being anti- sometimes means being a counterpart.

Recently, I was asked how many books I read every year. I usually deflect this question and come up with an answer like, “I don’t know, but I do know how many more I want to read.” I see this as a vanity metric, and I’m unsure why I would measure it. So, I tend to focus more on things that matter to me, and concerning books read, it might be the total number of books in my private library.

Italian philosopher Umberto Eco .... is the owner of a large personal library (containing thirty thousand books), and separates visitors into two categories: those who react with “Wow! Signore professore dottore Eco, what a library you have! How many of these books have you read?” and the others – a very small minority – who get the point that a private library is not an ego-boosting appendage but a research tool.

Read books are far less valuable than unread ones. The library should contain as much of what you do not know .... You will accumulate more knowledge and more books as you grow older, and the growing number of unread books on the shelves will look at you menacingly. Let us call this collection of unread books an antilibrary.

(from Nassim Nicholas Taleb, The Black Swan)

A bigger frame of mind.

I do like this frame of thinking. Given that we’ve recently arrived at the beginning of a new year, an event that inevitably imbues our culture with talk of reinvention and self-improvement, it seems an opportune time to look a little closer at this under-appreciated idea.

  1. Seeing how much more there is to know, learn, forget, and learn again is humbling.
  2. It also illustrates the cost of opportunity when choosing the next book to read.
  3. You can’t read all the books in there.
  4. It is also a good introspection tool.
  5. It’s easy to go to a random book, open a random chapter, and see what exciting things you can find hidden there.

And to read, we shall.

Some notes from me on how I read books:

  • If I pick up something to read, I will do it intentionally.
  • I won’t read if I can’t find a reason to read.
  • It is okay not to finish a book as long as I respect my reading process.

How do I build and maintain an antilibrary?

  • Create a framework for how you manage knowledge.
  • Time is a great filter.
  • Ask friends, colleagues, or fellow readers for similar books.
  • Let serendipity take control at bookstores.
  • Always remember that acquiring knowledge is a process, not a possession.

Thanks for reading so far! See you on the next one!
