Daniel E. Feinberg and Sarah Moukhliss write: “Historically, the role of online learning librarians (OLLs) has been ambiguously defined within the literature. This paper, authored by two OLL colleagues at the University of North Florida, aims to clarify the roles and perspectives of an OLL and a STEM OLL, thereby contributing to the clarity of their profession and the existing literature. The authors also explore key attributes that new professionals can develop to succeed in this dynamic role, addressing common questions posed by colleagues and faculty.”
