Someone decided to build a web page for every book ever published.
Not a summary. Not a review. A full catalog entry for each one — and for millions of them, a free digital copy you can borrow and read right now, the same way you'd borrow a book from a library.
Open Library is a project of the Internet Archive, the non-profit that's been archiving the internet since 1996. The mission is simple and staggering: one page for every book ever written. A universal library, on the internet, free and open to everyone.
3 million books are available to read or borrow right now. Classic literature. Out-of-print titles. Academic texts. Books that disappeared from print decades ago and exist nowhere else online. You borrow a digital copy for two weeks, return it when you're done, and it goes back to the next person in line — exactly like a real library, because that's what this is.
There's a barcode scanner for your phone if you want to look up a physical book you're holding. A "Random Book" button if you want to discover something new. Subject browsing, collections, reading lists.
Everything a library has ever been, in one place, for free.
Go find the book you've been meaning to read.
