Is it legal to copy content from other sites and post it on yours.Is it good enough if you give them the credit for it?
so everytime i want to get a article from some place, i need to have permission to publish it on my site too?supposedly i want to take an image from some other site, is it ok if i say courtesy:thesitesname.com after the image?
Some sites invite people to republish their content on other sites and ask for a link back. If you can't see this on a site then it's a copyright infringement and you site will get taken down. Even then you have to ask their permission before you republish the image.
You can copy content if there is statement on site allowing you to do so. It's important read the TOS of the site in question. Otherwise, you can't in overall terms.
Correct. However if the information in the article isn't confidential, you can reword the article & publish it.
All content needs to be viewed as copyrighted, unless there is an explicit statement on the page that says you are free to use the content or that it is in the public domain. Even if no copyright notice is shown on a page/site the content is still copyrighted. NEVER assume that something is not copyrighted. If you want to use anything on your site you need to get permission first. Even if you provide credit/link to the source it is not OK to use anything without obtaining permission first. That is true to a degree. However you need to be careful. Copyright also includes the creation of derivative works. Ideas and facts can't be copyrighted, but the expression of the ideas can. So if you take an article and "reword" it you might still be in breach of the copyright (depending on the situation of course). With images you are not allowed to make any derivative work. That includes altering an image in any way or using the image in another work.
The information that I read could very well be incorrect, but I did read a disclaimer, that quoted which ord number .. that stated that an article can be copied into a forum, or blog, etc, if the article was there for the purpose of discussion, actually i just posted looking for such a disclaimer, and would love to be able to read it again so I could research the info there and see if it is true.
You're likely talking about the "Fair use" doctrine, while is often incorrectly used to reprint others work without their permission. "Fair Use" cannot be used to reprint an article in its entirety in virtually all situations of a commercial website. Commerical means the site takes in some form of income (including adsense, advertising, memberships, donations for bandwidth, etc) - and most posters on DP aren't teachers asking about reprinting an article for their classroom, etc. You can post any type of disclaimer you want, but that doesn't make it legal. In the context of "can I reprint someone elses article on my website without their permission"- the short answer is no.
Yupperz that's what I was referring to, thanks for the clarification... I notice that you said 'in its entirety' .. care to elaborate?
For instance, you are allowed to quote passages for the purposes of "fair and reasonable criticism" (like a book review) or take short quotes from an article (giving the author and source credit) in some circumstances - which is obviously different than reprinting an article in its entirety. This doesn't mean you can take an article and change a few words, or omit a paragraph from the original article and republish it.
