This digest summarizes the more than 300 items in the ERIC database concerning writing across the curriculum (WAC) published between 1990 and 1992. The digest presents categories of material about WAC--advocacy, activities, recent research, implementing new programs, and faculty training--and discusses one or two pertinent sources for each category. The digest concludes that mounting evidence and reports of successful implementation of WAC programs suggest that the movement will continue to be important in the year 2000. (RS)
