The 1900 games were not governed by a specific Olympic organizing committee, but instead held as an appendage to the 1900 World's Fair. An enormous number of events was held, though many fall short of the standards later required for Olympic championship status. Decisions as to which Olympic events are termed "official" and which have "unofficial" or "demonstration" status are usually left to the Olympic organizing committees and/or the IOC. In the absence of any overall authority capable of making an official distinction of this kind, no decision as to the official status of any event was made at the time of the Games. A document from 1912 exists, listing results from the 1900 Games, but the reliability and authenticity of this paper is questioned by Olympic historians. This document formed the original basis of the results of the Paris games in the IOC database. However, the IOC has never decided which events were "Olympic" and which were not.
