able to accept unlimited private donations, all of which were tax deductible. Approximately $10 million of contributions came from Saudi Arabia. However, the Clinton Foundation declined to release a full donor list, similar to the Ronald Reagan Presidential Library (although the foundation later agreed to disclose the top 150 donors to the House Government Reform Committee). Donations exceeding $1 million were also given from various other foreign governments (such as Kuwait and Taiwan), as well as foreign individuals. Various American organizations also contributed millions of dollars to the foundation. Dedication ceremony The Clinton Presidential Center was dedicated on November 18, 2004. Although it was raining, the ceremony was attended by approximately 30,000 people (including notable figures such as Willie Mays, Robin Williams, and Barbra Streisand) and included a 20-minute speech made by Clinton, who had recently undergone bypass surgery. It also included performances by Bono, the African Drum Ballet and the Philander Smith Collegiate Choir, as well as an invocation given by Floyd Flake and video tribute from Nelson Mandela. Four U.S. presidents (Clinton, Jimmy Carter, George H. W. Bush, and George W. Bush were present; former president Gerald R. Ford could not attend due to health concerns) were on the same stage together. All three other presidents spoke at the event as well. Overall, the ceremony lasted two hours and featured six speakers. Fifth anniversary On November 17, 2009, the library's fifth anniversary saw Clinton giving a speech to approximately 1,000 people, urging the passage of health-care reform and the reduction of energy use. He specifically mentioned the center and school as places where discussion on such topics could take place. Complex Main building The five-story main building comprises of exhibition space, the Great Hall (used for banquets or forums), Forty Two (formerly Café 42, now a full-service restaurant; Clinton was the 42nd president), and classrooms. A private penthouse used by Clinton is located on the top (fifth) floor of the main building, one level above the public museum area. In 2007 the Clinton Foundation installed on the rooftop of the Presidential library the private "Rooftop Garden" with a golf course. The organization of the exhibits within the main building was inspired by the famous Long Room in the Old Library at Trinity College, Dublin, which Clinton first saw when he was a Rhodes Scholar. The Cadillac One used during Clinton's presidency is housed on the first floor. On
