Context
The Wayback Machine, developed by the Internet Archive and Alexa Internet, preserves the web by using web crawlers to capture and store snapshots of publicly accessible web pages. It cannot capture every page, its vast repository of over 330 billion web pages and millions of other digital items provides extensive resources for research and preservation, supported by global book-scanning centers. The Wayback Machine, developed in collaboration with Alexa Internet, is a core feature of the Internet Archive. It functions by creating a three-dimensional index that allows users to browse web documents across multiple time periods. This unique capability transforms the Wayback Machine into a digital time capsule, capturing and preserving the state of web pages over time. When a user accesses the Wayback Machine, they can enter a URL and view archived versions of that web page, showcasing how it appeared at various points in history.

The Internet Archive does not capture all websites on the web; its focus is on publicly accessible pages. Pages that require passwords, are accessible only through form submissions, or reside on secure servers are generally not included in the archive. Additionally, certain pages are excluded due to robots.txt files, which instruct web crawlers not to archive them, and some sites are excluded at the request of the site owners.
