11/12/2008: "Important AP Stylebook Update"
Please put the following AP Stylebook update in your copy of the book. It just came out today.
Editor's Note: The entry on president has been changed to say that the first and family name should be used on first reference to a current or former U.S. president or president-elect.
Capitalize president only as a formal title before one or more names: President Ronald Reagan, Presidents Gerald R. Ford and Jimmy Carter.
Lowercase in all other uses: The president said today. He is running for president. Lincoln was president during the Civil War.
FULL NAMES: Use the first and family name on first reference to a current or former U.S. president or the president-elect: former President Jimmy Carter, President George W. Bush, President-elect Barack Obama. On subsequent references, use only the last name.
For presidents of other nations and of organizations and institutions, capitalize president as a formal title before a full name: President Nicolas Sarkozy of France, President John Smith of Acme Corp.
On second reference, use only the last name.
