As the OER movement expands in higher education, libraries are increasingly seeking to add OER librarians to their organizational charts. As an emerging subfield, OER librarianship takes many forms, and there are many paths to OER work. This study examines OER librarians' paths to the field, including their motivations for entering and remaining in the field, their day-to-day work, and the barriers that they experience. The results of this study have implications for administrators seeking to develop or sustain OER programs in their libraries and on their campuses.
