One of the most reliable sources of information on all of the U.S. presidents is History.com. The site offers fact pages and live-actor videos on each president, and is regularly updated to reflect the most current facts available.
In addition to each president's page and video, there are dozens of other informative videos, detailing everything from the History of the First Lady to high-profile scandals, friendships and catastrophes. Other options on History.com include presidential fun-facts, birthdays, a "Find-Out More" section that offers less-known facts, and historical accounts of other happenings during each president's term in office.
Every president had to start with a campaign, and the "Path to the Podium" section chronicles where, and how, the roads to Office began, including details of what happens behind the scenes of a presidential debate, and what campaign slogans have proven to be the most successful. There is also a search option for anything not clearly available, or if a specific fact is needed. When the presidential research is complete, there is a video that teaches not only the history of the White House, but also how it was built, as well as a video that shares facts about the various presidential monuments.
