Newspapers have always had a combination of original and syndicated content.
Local newspapers have local reporters that write the local sections of the newspaper.
For national and international stories, newspapers rely on news syndications, like the Associated Press, for articles, comics, political cartons, photos and columnists.
Your websites can take advantage of this same process, greatly expanded to all forms of electronic media on the Internet.
You need to have a good idea of what is of interest to your readers and assemble the information in a way that is useful to them.
If you can add your original thoughts, even better.
