Library of Babel Explained: The Site With Every Text Ever

Updated October 12, 2026

The Library of Babel is a website created by writer Jonathan Basile in 2015 that simulates the infinite library from Jorge Luis Borges' 1941 short story of the same name. It contains every possible page of 3,200 characters made from 26 lowercase letters, the space, the comma and the period, which means any text you can type in those characters already exists somewhere in it, at a fixed address you can visit.

What is the Library of Babel website?

Go to libraryofbabel.info and you get a portal with three options: wander to a random book, browse the shelves by hand, or search for a piece of text. Open any book and you will almost certainly see pure gibberish. Search for your name, your birthday, or the first line of the essay you have not written yet, and the site will show you the exact page where it already lives.

The site's own count puts it at roughly 10 to the power of 4,677 books. For scale, that number has more than 4,600 digits. There are not enough atoms in the observable universe to write it out as physical books, not even close.

The Borges story behind it

"The Library of Babel" (La biblioteca de Babel) is a short story by the Argentine writer Jorge Luis Borges, first published in Spanish in 1941 and later collected in Ficciones (1944). It imagines a universe that is a library: an endless network of identical hexagonal rooms lined with shelves of books.

Each book has 410 pages, 40 lines per page and roughly 80 characters per line, built from a small set of symbols. Because the library holds every possible combination of those symbols, nearly every book is nonsense, yet somewhere on its shelves sits every true history, every lie, every book ever written and every book that ever could be.

The story follows the people who live there. They swing between joy at owning every answer and despair at never being able to find one. Some form cults, some destroy books they consider worthless, and some hunt for a legendary room of special books or for a librarian said to have read the perfect catalog of the whole library. It is a short read, and it is genuinely worth reading in full.

How can one website contain every text?

Here is the trick: Basile's library does not store any books. It would be impossible. Instead, it uses an algorithm that turns a location into a page of text, and back again.

• Every page has an address. A location is made of a hexagon name, a wall, a shelf, a volume and a page. Following the layout from the story, each hexagon has 4 walls, 20 shelves and 640 volumes.
• The address is the content. The page text is calculated from its address each time you open it, so the same address always shows the same page.
• It works in reverse. Type any text and the algorithm runs backward to produce the address where that text sits.

So the library does not "write" your sentence when you search for it. Mathematically, that page was always at that address. Basile has said the site does not generate books on request; every arrangement already exists in a fixed place.

How does search work on the Library of Babel?

1. Open the search page and type up to 3,200 characters.
2. Stick to lowercase letters, spaces, commas and periods. Those are the only characters the library uses.
3. Hit search and you get a location: hexagon, wall, shelf, volume and page.
4. Click through and you land on a full page where your text appears, usually surrounded by random characters.

One detail that makes it click: the hexagon names for searched text are enormous. Basile has explained that text you search for will almost always land in a hexagon whose name is itself around 3,200 characters long. The address is about as long as the text, because the address basically is the text in disguise.

There is also a sister project, the Babel Image Archives, that does the same thing for pictures: every possible image on a 416 by 640 pixel grid using 4,096 colors.

Why is the Library of Babel so mind-bending?

• Everything is already written. Your diary, tomorrow's headlines, a perfect review of a movie that does not exist yet. All of it, at a fixed address.
• And it is all useless. For every meaningful page there are unimaginably more that are nonsense, plus near-copies with one typo. A library of everything is also a library of nothing you can find without already knowing what you want.
• It flips what "writing" means. If every sentence is already there, is writing just finding a page? That is the question Borges was poking at in 1941, and the website lets you feel it.
• Random browsing never stops being creepy. Every so often a real word or two floats up out of the noise, and your brain tries to find meaning in it.

Tips for exploring the Library

• Search something personal first. Your name or a favorite lyric is the fastest way to get the "wait, what" moment.
• Bookmark the page you find. Because addresses never change, you can share that exact page with a friend.
• Try random books. It is the closest thing to walking the shelves in the story.
• Read the story too. The site makes way more sense, and is way more unsettling, once you have read Borges.
