The term embedded librarian describes a variety of service models in a variety of organizational settings. Embedded librarian service models often include an academic librarian who participates in an academic course on an ongoing basis, teaching information literacy skills. These courses often hold assignments that serve both the learning goals of the course and extensive knowledge of library resources. The role focuses on providing services to user groups away from the physical library, so that they can work more closely with the members of those groups .
Similarly, an Informationist is best known as a medical or health sciences librarian who also has a subject-specific background in a biomedical discipline that serves as part of a clinical or biomedical research team. The purpose of the Informationist is to bring expertise in library resources and a strong knowledge of a subject discipline to serve as the information professional on a team. Their role can include searching for literature, building information literacy through teaching, providing data management services, and assisting in the overall research process. Like an embedded librarian, an Informationist is usually stationed within a research team as opposed to within the actual library. Recently that National Library of Medicine has supported the role of the Informationist by providing grant opportunities to health sciences librarians who may be suited for this particular role.
