The Second Edition continues to explore key challenges facing the profession, such as earning the trust and respect of critics and the general public. Much greater emphasis and space will be placed on a theme that was just emerging when the First Edition appeared: the Internet and social media as public relations tools. International coverage and representation has been greatly expanded, as well. Finally, biographies (which are now widely available on the Web) have been deleted to give room to areas of enhanced coverage, and biographical material are included where appropriate within the context of topical entries. However, a long entry on women pioneers in public relations has been included as an appendix.
