In many cases, the initials only are given in place of the forenames for the personal author entries -the "initial method". We find many abstract journals which employ the initial method in the abstracts and indexes. The method is also employed by the International Nuclear Information System, of which Japan is one of the member states. For the Romanized author names, the method causes many duplications, and the rate of duplications is about 25%, This large duplication is due to the fact that the names of Japanese people have only one forenames and that the Romanized names can substitute the original name only when it is accompanied by the latter one in Chinese characters. The initial method cannot be used for the Japanese author names, in a personal author index, for instance, when the number of papers by Japanese authors is over several hundreds. Names of the authors other than Japanese may be entered by the initial method.
