[WRG-Art]

Hi all, ive got my dissertation coming up for my final year of Uni. I'm currently trying to sort my proposal out by finding sources, e.g. reference books, text books etc. my title is "How has the blending of traditional and digital media helped progress the field of concept art". Long and short of it, does anyone know any books they could recommend to help? As i am struggling at the moment to find much. All help is greatly appreciated, cheers guys
