The Internet Archive is an American digital library founded on May 10, 1996, and chaired by free information advocate Brewster Kahle. It provides free access to collections of digitized materials like websites, software applications, music, audiovisual and print materials. The Archive is also an activist organization, advocating a free and open Internet. As of January 1, 2023, the Internet Archive holds more than 36 million print materials, 11.6 million pieces of audiovisual content, 2.5 million software programs, 15 million audio files, 4.5 million images, 251 thousand concerts, and over 808 billion web pages in its Wayback Machine.
The Internet Archive allows the public to upload and download digital material to its data cluster, but the bulk of its data is collected automatically by its web crawlers, which work to preserve as much of the public web as possible. Its web archive, the Wayback Machine, contains hundreds of billions of web captures. The Archive also oversees numerous book digitization projects, collectively one of the world's largest book digitization efforts.
