Exploring Digital Library Adoption Intention through UTAUT: A Systematic Review

Digital libraries (DLs) play a crucial role in university education and research, making it necessary to understand the factors affecting users' intention to use them. Literature reviews are crucial in this regard. However, limited systematic reviews using Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) on university DL acceptance were studied using the Unified Theory of Acceptance and Use of Technology (UTAUT) framework and its variants. UTAUT encompasses eight models/theories used to study IS with high explanatory power. This study mainly aims to 1) classify the existing literature according to the factors studied, 2) identify the confirmed relationships among the factors affecting usage intention, 3) identify the countries studied, and 4) suggest future research in this area. The study reviewed 28 publications selected from 181 studies identified from two commercial databases and Google Scholar. In addition to applying inclusion/exclusion criteria, a quality assessment of the selected studies was done to ensure that the quality differences do not affect the study results. All 28 studies passed the quality assessment. Among the factors influencing DL usage, 'facilitating conditions' emerged as the most extensively studied factor, while the effect of performance expectancy on usage intention has been confirmed the most. Finally, the behaviour of each affecting factor has been discussed, and the way forward has been signposted.
