Search time dependencies in hypertext on the correspondence of the terms of links, the number of hierarchies of links, and the amount of information on the last page were examined experimentally. Among these three effects, the effect of the correspondence of the terms of links was the greatest. In this experiment, the search time ratio of the best corresponding terms to the worst was 16 : 1. The lower the target information on the last page, the longer the search time ; however, the effect of the amount of information is not so great. Although the ratio of the greatest number of characters to the least number of characters to the target information was 28 : 1 in this experiment, the longest search time was only 5 times that of the shortest. When the target information is located at the bottom of the last page, it is efficient to divide information using several links to reduce the search time. On the other hand, when the target information is located at the top, it is not efficient or rather has an inverse effect to divide information using several links.
