Communication Arts asked leading designers, representing a cross-section of the profession, to share the top ten sites they consider vital to their work. Culled from more than 500 suggestions, the 50 essential bookmarks was originally published in the Communication Arts November Design Annual 2006. The list is divided into categories to help navigate the Web.
