This book provides theoretical models and practical methods for helping writing teachers and writing program administrators within postsecondary institutions conduct the interdisciplinary, collaborative consulting activities that are common with formal and information writing across the curriculum (WAC) programs. It specifically discusses how to conduct the day-to-day work of negotiating close working partnerships with faculty in other disciplines and is the first book length treatment to do so. The book deepens current understandings of how writing specialist collaborate with non-writing specialists in academic contexts and provides a map for structuring successful collaborations in the future.
