I found a story on www.nicar.org about how the White House has lost some of it's records on who has come to visit. The story is based on looking through the log of people that must provide their names and reasons for visiting the White House. Someone noticed that there were many names that are not there, and some names thats shouldn't be there. Since these records were held as reliable for so long, it makes people question whether or not they have always been accurate. The reporter would have needed to have access to the records online and have had computer skills for researching the subject to find if this was true. They also posted a text link in their story to a picture, which also requires some computer skill.
