If you like to use curated content in your blog posts then this article from curata.com is a must read. There are differences between sharing an article, (which is writing an introduction to an article and then sharing the link - like this one), and a curated post. A curated post involves a few more steps. And it's important to make sure that you follow those steps to avoid the possibility of copy-writing. There are a lot of articles out there about the best practices for a curated post, but this one, complete with info graphic, covers all the points beautifully.
