[Purpose/significance] The purpose of this research is to reveal characteristics of the query formulation behavior of mobile library users and to make some suggestions to improve the search function of the mobile library application. [Method/process] The characteristics in terms of the query relevance, query reformulation, query topics and request duration are examined by statistics of the mutual information, query diversity, query richness, topic distribution and duration time, based on the mobile library log mining of an academic library over a period of one month. [Result/conclusion] The mutual information statistics of mobile library users' queries are low, which means every query relates weakly semantically. The most common reformulation model are the Repetition in terms of adjacent queries and the Straight Line in terms of queries in a search session, which means mobile library users tend to search the same query for many times. It is found that mobile library users are interested in the information about humanities and social sciences, and they often search the same topic continuously. Thus, the paper suggests the search function of mobile library application add query recommendation, auto-correction, multiple search fields and advanced search.
