This article proposes a model for collaboration between composition instructors and instructional librarians to promote visual literacy instruction in first-year writing courses. While the creation of visual content is essential to digital composing technologies, it often remains underutilized as a tool for writing development in first-year curricula. Drawing from complementary threshold concepts outlined in composition scholarship and the ACRL Framework for Information Literacy , we demonstrate how librarians and writing instructors can engage in collaborative instruction to bridge gaps between theory and practice and leverage existing institutional expertise to support multimodal instruction in first-year writing.
