Abstract: The purpose of this study is to identify the significant dimension of LibQUAL+ that has a greater influence on hospitality students’ satisfaction towards the quality of the overall service provided by a library. Authors of this study have used a modified (a shorter performance-only) LibQUAL+ tool to measure the perceived service quality of a library. The data for this study is collected from both graduate and post-graduate students from a single hospitality institute in Karnataka, India. The regression analysis is used to test the hypotheses. “Affect of Service” emerged as a significant dimension accounting for hospitality students’ satisfaction. The study gives practical insights to library managers about students’ perceptions of service quality for improved decision-making and helps them to reallocate human resources effectively by identifying the most important predictor of library service quality.
