This study contributes to our understanding of the early experiences of teacher-librarians and brings in the framework of possible and provisional selves as a lens to examine teacher-librarian identity. Participants told us their strongest memories included professional development, advocacy, professional change, making the library a safe space focused on learning, supporting staff and students in taking risks, and collection development. Barriers and challenges included technology, library time and budget cuts, making changes in the library, and sharing the TL position with another teacher. We saw these teacher -librarians modeling, presenting, providing evidence, creating safe learning spaces, helping staff take risks, becoming more confident in their abilities, and meeting the needs of their school community.
