The Electronic Frontier Foundation has published For Freedom's Sake: Legal Guide for Bloggers a must-read guide for bloggers, podcasters and others who write content. This online guide tells all -- what is fair use, libel, what are the responsibilities of bloggers for using content created by others? If you have ever wondered, if you, as a blogger, can get access to information or a press pass to cover events, this is the guide for you.
Ignorance is no justification for breaking the rules. In my opinion we as bloggers do ourselves a favor by knowing and paying attention to the such issues. Read it, if for no other reason than it is interesting reading.
