Illustration Now! by Julius Wiedemann (editor) is a handy resource book highlighting the work of 150 of the world's best commercial and editorial illustrators today. Contact information, as well as work history and samples, is given for each artist presented in this book, but it is quite easy to ignore its usefulness altogether and gawk at the pictures. After all, that's what illustration is all about.
