Like a paper library, we provide free access to researchers, historians, scholars, people with print disabilities, and the general public. Our mission is to provide Universal Access to All Knowledge.

We began in 1996 by archiving the Internet itself, a medium that was just beginning to grow in use. Like newspapers, the content published on the web was ephemeral – but unlike newspapers, no one was saving it. Today we have 25+ years of web history accessible through the Wayback Machine and we work with 950+ library and other partners through our Archive-It program to identify important web pages.

As our web archive grew, so did our commitment to providing digital versions of other published works. Today our archive contains:

  • 625 billion web pages
  • 38 million books and texts
  • 14 million audio recordings (including 240,000 live concerts)
  • 7 million videos (including 2 million Television News programs)
  • 4 million images
  • 790,000 software programs

Anyone with a free account can upload media to the Internet Archive. We work with thousands of partners globally to save copies of their work into special collections.

Because we are a library, we pay special attention to books. Not everyone has access to a public or academic library with a good collection, so to provide universal access we need to provide digital versions of books. We began a program to digitize books in 2005 and today we scan 4,000 books per day in 18 locations around the world. Books published prior to 1927 are available for download, and hundreds of thousands of modern books can be borrowed through our Open Library site. One of the Internet Archive’s missions is to serve people who have difficulty interacting with physical books, so most of our digitized books are available to people with print disabilities.
