Veterans constitute a significant group in society, and reports have shown that the number of disabled veterans keeps increasing. More than 50,000 United States troops have been injured since the wars in Iraq and Afghanistan began and the numbers will increase until the troops are withdrawn (Geiling, Rosen, & Edwards, 2012). Consequently, services to disabled veterans remain very crucial to information service providers. The goal of this study is to analyze the barriers and challenges that disabled veterans face when using library services. This study used the Student, Environments, Tasks, and Tools (SETT) framework to explore how disabled veterans interact with library services (Zabala, 1995). Two surveys were conducted to provide data for a critical examination of the four elements (veteran, library, tasks and assistive tools) that provided insights into how librarians can better understand veterans with disabilities within the library setting. This study also captured and compare both the librarians' and the disabled veterans' perceptions of library services. The major contribution of this study is the creation of the Veteran, Library, Tasks and Tools (VLTT) model which helps librarians to better understand and support disabled veterans' information seeking within the library environment.
