This article encourages thoughtful discussion on cross-disciplinary partnerships among those researchers, practitioners, and librarians engaged in the Scholarship of Teaching and Learning. Through personal experiences, examples from the literature, and the goal of meaningful collaboration, the authors describe four models of engagement with librarians in the Scholarship of Teaching and Learning. We propose that it is time for the Scholarship of Teaching and Learning and its practitioners to more fully engage with librarians because they bring complementary perspectives, powerful areas of expertise, and significant insights into students' learning experiences.
