Many journalism organizations offer ethics guidelines, including the Canadian Association of Journalists, which has both a general statement of principles for ethical journalism and an expanded ethics guidelines. 

Some other journalist' codes of conduct include:
Society of Professional Journalists (USA)
National Union of Journalists (UK)
Journalism Code of Ethics (New Zealand)
RTNDA Canada's Code of Ethics for electronic journalists
Guide de déontologie des journalistes du Québec (FPJQ)
Communications Workers of America, Canada (includes several newspaper and media guilds)
Communications, Energy and Paperworkers Union of Canada (CEP Media/Canadian Freelance Union)
National Society of Newspaper Columnists Code of Conduct (North America)
Association of Opinion Journalists Basic Statement of Principles

Many major news organizations provide guidelines for editorial staff, though not all these documents are available to the public. Of special interest may be the ethics guidelines of The Canadian Press and The New York Times Company.

None of these codes is intended as, or useful as, a rule book for every occasion. Lists of guidelines may help in clarifying some widely accepted norms of practice, but journalists' work calls for frequent decisions of individual and collective conscience which often involve balancing conflicting values and analyzing complex situations. Still, as Stephen J.A. Ward has suggested, codes can, if incorporated into newsroom discussions, inform moral reasoning and promote public accountability.
