PresidentsUSA.net, the White House site and the Library of Congress site have a list of the Presidents of the United States in chronological order. The first two lists are numbered, so users can quickly find which number each President was.
PresidentsUSA.net has a simple list of all presidents and vice presidents. Each name is a link to a page of quick facts that link to other pages with more information. The main list can be sorted by political party, and within each party, the presidents are listed in chronological order. On each individual's page, there is a drop-down box where users can pick a different president.
The White House list is broken up by century, making it easier to find a specific time period of presidents. Each name links to a page with detailed information about the president, such as a biography and political views. The pages also feature a picture of the president.
The Library of Congress list includes vice presidents and first ladies, most with linked names. The links go directly to an image of the person. Years of service are listed along the left-hand side of the chart, and those who served multiple terms have an entry for each term.
