This research paper examines the validity of the use of bibliometric law for research on bronchitis literature worldwide. The various bibliometric laws of the lotka’s law and Zipf's law in their mathematical expressions often present difficulties in adapting the observed values. The result indicates that the author's productivity according to Lotka's law is consistent with research on bronchitis literature worldwide. The law of the price square root is not applicable with the author's productivity information. Zipf’s law was applied to identify publications about the frequency of word occurrence.
