Associated Press
The AP website has a job listing page.
Copydesk
Copydesk is a freelance placement agency, but samples of their available gigs are shown on this page.
Freelance BBS
Freelance BBS requires a signup/registration, but I haven’t got any junk mail (yet) and am happy with the leads.
Freelance Switch
This job board is the only subscription service that I am including in these links, but it’s because I firmly believe in it. For $7 a month, you cut down on the sheer amount of people you are competing against. I got a job from here my very first month, making a 50x ROI over the long run.
Freelance Venue
This site has one or two new jobs per week.
