I also would think a financial profit would need to be made, yes?!</end quote></div>
Sometimes whether a profit is being made makes a difference in whether the author wants to take legal action, but a person does not have to be making money from someone's work in order to be infringing on copyright. As far as the fair use thing, again, that's such a gray area and is difficult to pin down from a legal standpoint.
Let me give you an example of a problem I recently had regarding copyright infringement. I published an original article with a certain media source online. It was a one time printing rights, meaning that if I wanted to have it published elsewhere I could do that too. So, I submitted the same article to another source letting them know of the other place I'd published it.
It was rejected. They claimed that my article had been published other places than what I had disclosed. A quick Google search on my own time proved that in fact, my article in its entirety was posted on someone's website without my permission. Although that website was not making money from positing my material, their act of copyright infringement had hurt my ability to make money from the article. (It wasn't a lot of money, but when you're working freelance we have to take what we can get sometimes)
Like Risa said, there are a lot of rules to follow. I wish I knew the details of all of them, but really it doesn't have much bearing on this forum to discuss it here. Bottom line is that we should all do what we can to be sure we share online content in appropriate ways. Summarize things in your own words and provide author information and links whenever possible.
Thanks!
