PurposeThis study aims to examine if differences exist in undergraduate students' library use, perceptions and grade point average (GPA) among science, technology, engineering and mathematics (STEM) and non-STEM disciplines.Design/methodology/approachThe current study used data from the 2018 student survey. Among 2,277 students who completed the survey (response rate = 8%), only undergraduate students (n = 1,265) were selected for this study because the current study aims to examine the differences between STEM and non-STEM undergraduate students.FindingsThe findings from a Mann–Whitney U test revealed that STEM respondents perceived specific library resources (subject and course guide, library instructions and library workshops) as slightly less than non-STEM respondents. The results from ANOVA demonstrated that the mean scores in GPA for STEM respondents who never used online library, journals and databases were lower than respondents who used those library resources, regardless of STEM and non-STEM disciplines.Originality/valueRevisiting the data collected and analyzing specific user groups will be valuable to academic libraries because this study will provide academic librarians with a deeper understanding of specific user needs and perceptions of library resources and services.
