You might begin by visiting the WAC Clearinghouse (http://wac.colostate.edu) to check out some of the resources there. The Clearinghouse offers a bibliography, links, and information about specialized initiatives such as Writing Fellows programs. It also offers a wide range of scholarly resources on WAC, CAC, and ECAC, including journals and books.
Although it’s not directly relevant to starting or renewing a program, you might also check out Kate Kiefer’s introduction to WAC, also available at the Clearinghouse. It addresses a number of issues that might concern faculty who would be an important audience for WAC initiatives.
