Abstract

This study analyzes the impact of environmental legitimacy in public libraries on user satisfaction and loyalty using a structural equation modeling (SEM) approach. The main variables include environmental legitimacy, library image, reputation, satisfaction, and loyalty. The analysis revealed that environmental legitimacy significantly and positively contributes to both library image and reputation. Furthermore, library image was found to have a positive effect on user satisfaction, and reputation also exerted a significant influence on satisfaction. In turn, satisfaction strongly enhanced user loyalty. These findings suggest that as public libraries strengthen eco-friendly management and sustainability practices, their image and reputation are reinforced, which ultimately translates into greater user satisfaction and loyalty. Therefore, implementing environmental responsibility and managing institutional image emerge as key strategic tasks in library operations.
