Internet Archive is a non-profit digital library founded in 1996 by Brewster Kahle in San Francisco. Its mission is to provide universal access to knowledge through the preservation of websites, books, software, audio, and video. Since 2001, it has consolidated its role as a repository for the ephemeral memory of the web, capturing millions of pages that would otherwise have disappeared. Its relevance lies in the historical reconstruction of vanished services and the documentation of digital culture from the 1990s and 2000s, allowing researchers and the general public to access original versions of web pages, technical manuals, and digital publications that define the cultural context of the early internet era.
