This study is aimed at identifying the impacting factors on student volunteers at an academic library in the Mekong Delta, Vietnam. Underpinned by the conceptual framework of volunteer and volunteering defined by Wilson (2000), the study was carried out using quantitative methods. Through emails and in-person meetings, a survey questionnaire was delivered to all volunteers in the LRC. There were 100 responses which reach the ideal samples as noted by Hair and his colleagues (2009). Data collected in this study were analyzed using SPSS with Cronbach’s Alpha, Exploratory Factor Analysis and multivariate regression to determine factors influencing students' decisions and their impacting level to volunteer at the library. Research findings indicate two factors influencing on student volunteering are experiences and relationships. An evaluation research on quality of student volunteering will be proposed to further research, so as to get further information about how productively the student volunteers can support their library. This study fills the gap by examining the impacting factors on volunteering that benefits the LRC and volunteering students. As a result of this influence, students are expected to know more about benefits and responsibilities of volunteering at the library, thereby obtaining greater experience, communication ability and confidence in their future work and life. This research contributes to literature about impacting factors on the student volunteers at the academic library in an Asian country context, which has not been discussed so far. It also provides possible solutions to attract and retain the student force for the library functions.
