A teacher librarian (TL) is a valued member of a school community because they are able to effectively support 21st century learning through the promotion of literature, learning and literacies. However, in order to do so effectively, a TL should be themselves a lifelong learner, have the capacity to collaborate effectively with their peers, ensure that the collection meets the needs of the community, have a keen interest in emerging technologies and be able to competently lead innovative pedagogies by modelling best practice. Most importantly, a good teacher librarian is a teacher first, because educationis at the heart of a teacher librarian’s practice.
