Improving the information literacy and writing skills of undergraduate social work students continues to be an issue for social work educators. In spite of the persistent concern, only a few studies examine the factors influencing these skills and interventions to strengthen them. This article details a faculty-librarian collaborative teaching model to develop students' information literacy and writing skills through an iterative, peer-reviewed process that includes online and in-class library instruction. Pre- and posttest results from course evaluations, using the learning management system, indicate that students improve their information literacy skills, which in turn improves their writing skills. The article concludes with a discussion of implications for academic and professional development.
