We know that unaffiliated users access books, reference services, and databases at our libraries, but how do they experience this access? The library science literature reveals a range of ethical concerns around how we serve unaffiliated users, meaning those who are not current students, faculty, or staff. Yet this literature is often based on librarian perspectives rather than on conversations with the unaffiliated users themselves. In this pilot study we interviewed 10 unaffiliated users to better understand their perceptions of a large academic library and how the library fits into their daily habits. Emerging patterns include a respect for the depth of academic collections, an appreciation of how physical spaces shape their campus experience, and a persistent sense of "nonbelonging" as people who are not students at our university--even if they are affiliated to another institution. In conclusion, we suggest ways that librarians can invite unaffiliated users onto campus as guests in the academic library community.
