The Comic Book Legal Defense Fund -- tireless free speech crusaders who fight for comics' legitimacy -- commissioned a great educational resource about comics' role in literacy called Raising a Reader (PDF).
This new resource is written by Dr. Meryl Jaffe, with an introduction by three-time Newbery Award honoree Jennifer L. Holm (Babymouse, Squish) and art by Eisner Award winner Raina Telgemeier (Smile, Drama) and Eisner Award nominee Matthew Holm (Babymouse, Squish). Raising A Reader! was made possible by a grant from the Gaiman Foundation.
You can get print-ready digital files from the Foundation, and they'll have print copies at at San Diego Comic-Con.
