Leading reference source on those who have occupied the White House and the institution of the presidency. In the two decades since it was first published, CQ's Guide to the Presidency has become the leading reference source on the persons who have occupied the White House and on the institution of the presidency itself. The Guide is extensively updated to bring the story of the presidency: [yen] through the partisan and tumultuous second term of Bill Clinton that was defined by only the second impeachment action in the nation's history [yen] through the controversial elections of 2000 eventually decided by a Supreme Court decision [yen] into the remarkable early months of President George W. Bush, who witnessed his presidency transformed in a single day on September 11, 2001.
