Please move this thread if I put it in the wrong section.

I have been thinking about adding a news section to my blog. Because of time constraints, I won't be able to write any of the news stories myself. Is there any way I can use one of the local news providers' articles? I will give credit on all the articles, but I want to know a bit more about legal implications. Would I need permission first, or would a "Source: " link be sufficient? Are there any providers that offer free content for your blog?
