A Wayback Machine (or a Web archival replay tool) is a software component that allows users to search by URL and
date, and to play back an archived version of a Website in a Web browser. It enables the replay of historic collections,
that are invaluable to everyone that needs to retrieve a past version of a Web site. Some possible use cases include a
journalist revisiting past cases, an historian analysing digital historic documents, or even a user that discovers a broken
link of a live Web page and tries to recover the missing content from a Web archive.
