Hi! The couple of ideas I have for a manual would include many examples, hints, and tips on business subjects (advertising, business cards)that I've collected and written down over the years. How can I incorporate those into a manual without getting into copyright trouble? I have NO IDEA where I originally heard of most of them.
I was told that IDEAS can't be copyrighted, but that a particular ILLUSTRATION of an idea CAN. Is this true?
And do you have to get permission to quote a text-based source, or just given them credit?
