Archive-It (Internet Archive)
The Internet Archive's subscription archiving service, used by more than a thousand libraries, governments, and universities to build curated web collections that together hold tens of billions of documents. Captures are viewed through replay links on wayback.archive-it.org, organized by collection. It pays off when a specific institution's collection covers your subject; coverage is collection-by-collection, so it is not the place to look up arbitrary URLs.

Por que é útil e como funciona
Archive-It is where institutions such as universities, government bodies, and libraries build and maintain their own focused web collections, so it excels when your subject falls within a specific organization's collecting area. Over 1,000 partner institutions worldwide have created more than 10,000 public collections, all of which are full-text searchable on archive-it.org. You can browse by organization or topic, then view captures through a Wayback-style replay interface. Because coverage is collection-by-collection, it works best when you have identified a relevant collection rather than when searching for an arbitrary URL.
O que há dentro
Partners have archived tens of billions of documents collectively. The service has been growing since 2006 and the combined holdings span petabyte scale, though a single aggregate figure is not published separately from the broader Internet Archive.
