It captures and saves snapshots of websites over time. Users can explore old versions of websites dating back to 1996.<\/p>\n<p>This tool offers a unique look at how the internet has changed. It lets you see websites as they were in the past.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<div>\n<h3>How many web pages does the Wayback Machine archive?<\/h3>\n<div>\n<div>\n<p>As of 2023, the Internet Archive has saved over 737 billion web pages. It\\&#8217;s the world\\&#8217;s largest digital preservation project.<\/p>\n<p>The archive adds about 1-2 billion new web pages every week.

The Wayback Machine only captures public web pages. Some content might be missed due to various limits.<\/p>\n<p>Websites that block web crawlers or have login walls may not be saved. Pages with robots.txt restrictions might also be missed.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<div>\n<h3>How can I use the Wayback Machine to view an old website?<\/h3>\n<div>\n<div>\n<p>Go to archive.org and type the website\\&#8217;s URL in the search bar. You\\&#8217;ll see a calendar showing saved versions of that site.<\/p>\n<p>Click on any date to view how the website looked at that time. It\\&#8217;s like traveling back in time!<\/p>\n<\/div>\n<\/div>\n<\/div>\n<div>\n<h3>Can websites request removal from the Wayback Machine?<\/h3>\n<div>\n<div>\n<p>Yes, website owners can ask to remove their content from the archive. The Internet Archive has a process for this.<\/p>\n<p>Copyright holders or site admins can submit a formal request. They can ask to have specific archived pages taken down.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<div>\n<h3>Are there APIs available for researchers and developers?<\/h3>\n<div>\n<div>\n<p>Yes, the Internet Archive offers several APIs. These allow developers and researchers to access archived content through code.<\/p>\n<p>Available APIs include the Wayback Machine CDX Server API and Save Page Now API. These tools enable advanced use of the web archive.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<div>\n<h3>How long are web pages typically stored in the archive?<\/h3>\n<div>\n<div>\n<p>Once captured, web pages are usually kept forever. But the frequency of snapshots can vary.<\/p>\n<p>Popular sites might be archived multiple times daily. Less active sites may have fewer saved versions.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<div>\n<h3>Is the Wayback Machine completely free to use?<\/h3>\n<div>\n<div>\n<p>Yes, the Wayback Machine is free for everyone. Anyone can browse old websites at no cost.<\/p>\n<p>The Internet Archive, a non-profit, runs this project.
