There are various better known collections at the Internet Archive. These are some of them.
(once they are added here)
The IA's by far best known project is the Wayback Machine, a viewer for saved snapshots of websites dating from the present back to the early 1990s.
The IA contains a large Software Library, with a wide set of historical software available to be run directly in the browser.
Another IA project is Open Library a catalog of (eventually) all books, which provides an interface to access scans of the many books stored at IA, both freely (for public domain or freely licensed works) and via Controlled Digital Lending (for in-copyright books, using fair use and first sale).
