^ A: The IOC site for the 1900 Olympic Games[1] gives erroneous figure of 95 events, while the IOC database for the 1900 Olympic Games[2] lists 85. Probably this discrepancy in IOC data is consequence that the figure 95 just derived from the "1900 Olympic Games — Analysis and Summaries"[3] publication of Bill Mallon, who used his own determination of which sports and events should be considered as Olympic.
^ B: The IOC site for the 1904 Olympic Games[4] gives erroneous figure of 91 events, while the IOC database for the 1904 Olympic Games[5] lists 94. Probably this discrepancy in IOC data is consequence that the figure 91 just derived from the "1904 Olympic Games — Analysis and Summaries"[6] publication of Bill Mallon, who used his own determination of which sports and events should be considered as Olympic.

Note: Although the Games of 1916, 1940, and 1944 had been cancelled, the Roman numerals for those Games were still used because the Summer Games' official titles count المپیادs, not the Games themselves, per the Olympic Charter. This contrasts with the Winter Olympic Games, which ignore the cancelled Winter Games of 1940 & 1944 in their numeric count.
