    1. Thank you for your question. The U.S. National Archives does not take a snapshot of everything on the internet. We only collect federal records, which are records generated by the federal government and government agencies. The following paragraph from the “Our Holdings” section of the About the National Archives webpage provides some information on the magnitude of our holdings:

      “NARA keeps only those Federal records that are judged to have continuing value—about 2 to 5 percent of those generated in any given year. By now, they add up to a formidable number, diverse in form as well as in content. There are approximately 10 billion pages of textual records; 12 million maps, charts, and architectural and engineering drawings; 25 million still photographs and graphics; 24 million aerial photographs; 300,000 reels of motion picture film; 400,000 video and sound recordings; and 133 terabytes of electronic data. All of these materials are preserved because they are important to the workings of Government, have long-term research worth, or provide information of value to citizens”
