Open Library is a project by the Internet Archive aiming to create a web page for every book ever published. It offers millions of books you can read, borrow, or preview for free through Controlled Digital Lending.

What makes it stand out:

• Massive catalogue — 3M+ books available to read or borrow

• Full‑text search across millions of digitized works

• Reading log & lists to track what you’ve read and want to read

• Virtual Library Explorer with shelves arranged like a physical library

• Community‑driven — anyone can edit metadata, add books, or help improve the catalogue

• Multilingual interface with dozens of supported languages

• Part of the Internet Archive, alongside the Wayback Machine and Archive‑It

If you love books, open data, or digital preservation, this is one of the most valuable free resources on the web.
