As librarians' instructional responsibilities diversify, it is useful to consider what factors influence how they see themselves as educators. In this research, the author used a survey instrument grounded in transformative learning theory to explore what factors librarians who provided online or blended/hybrid instruction felt had impacted their teaching identities. She found statistically-significant differences between these librarians and their peers who provided face-to-face instruction in the relationships, experiences, and professional components that influenced their educator identities. By better understanding these influences, we can more intentionally support academic librarians who teach online or in blended/hybrid environments.
