^ B: The IOC site for the 1904 Olympic Games^[11] gives erroneous figure of 91 events, while the IOC database for the 1904 Olympic Games^[12] lists 94.

"ملاحظة: على الرغم من أن الألمبياد أعوام 1916، 1940 ، 1944 ألغي، لا تزال الأرقام الرومانية مستخدمة لترقيم هذه الدورات لأن الترقيم يكون للأولمبياد نفسه وليس للألعاب، وذلك حسب ميثاق الألعاب الأولمبية. وهذا يخالف دورات الألعاب الأولمبية الشتوية حيث ألغي الترقيم في الدورات الشتوية 1940 و1944.
