know of anywhere i can get authors

It depends on what Theme/Topic your website/blog would deal in.

Also you can post your requirements on various forums dedicated specially for "Wants" posts. I'm sure you will run into many Authors who are willing to posts on your blog. they just need a good flatform.

Good luck.

post those articles by splitting or editing it.

No it's not. It is still duplicate content. The bottom line is if you use unoriginal content that content will not help you with SEO as it will be essentially filtered out and devalued tot he point of worthlessness.

If you edit each sentence with at least 30% difference, it will work for sure. Just try to rewrite everything by yourself, even the author's copyright will not apply, also in this case no link needed )))

In the time it would take you to make the kind of changes to make the article seem unique you can write the same article yourself and make it even better. Plus the articles that are freely available are rarely very good and never link bait. Why not just write one good article for yourself that will actually be high quality and attract links? You will get a lot further that way.

In my case I have pages with biographies of italian fashion designers. It is not something that i can write as an article. But i can rephrase alot. And it worked those pages are not supplemental and attract alot of hits. And math formulas or poetry or citations for example can't be considered as dup. content.
