Examining differences and similarities between graduate and undergraduate students' user satisfaction with digital libraries

Informed by the theories of Information System Success, Technology Acceptance Model (TAM) and Affinity, this study aims to explore the differences and similarities between graduate and undergraduate students' satisfaction with digital libraries (DLs). Descriptive statistics and One-way ANOVA were employed to analyse 426 valid responses collected from a survey. The results indicated that compared with undergraduate students, graduate students were more satisfied with digital libraries' system quality, information quality, and service quality, affinity, perceived ease of use, and perceived usefulness. Individual differences of users, such as age, frequency of use and use experience, had a significant impact on undergraduate and graduate students' satisfaction with digital libraries. University librarians and service providers should notice the similarities and differences between undergraduate and graduate students' satisfaction with digital libraries, and improve the system, information and service quality of digital libraries to increase the perceived ease of use, perceived usefulness, and digital libraries' affinity, thus to enhance user satisfactions.
