What objectives or questions do each address?
Lundrigan, Manuel and Yan sought to evaluate user satisfaction of a particular web discovery system known as Summon at Ryerson University. On the other hand, Hossain had several research questions to guide his research. He also outlined two objectives of the study. The research questions were; Which service items fall short of users’ expectations? What are the causes of user dissatisfaction? What are the possible measures that may contribute to user satisfaction? The two main objectives he sought were; To identify the causes of user dissatisfaction of services delivered by academic libraries; and to recommend the measures that may lead to user satisfaction.
How have the authors chosen to define “user satisfaction” for their studies?
Lundrigan, Manuel and Yan defined user satisfaction as ‘a measure of the value of their investment.’ Hossain defined user satisfaction as the degree to which library meets its users needs and expectations. Ludrigan, Manuela and Yan pegged their definition of user satisfaction on the value drawn by users from a service.
