copyright laws and answer books? Answered
I want to write answer manuals for textbooks that don't provide the answers in the back in my fields of physical science and math. I want to make my own answers, proof check with others, and probably e-publish it.
My question is on the legality of doing this. The copyright aspect pertains to the questions themselves. The answers are all original on my part. Now I suppose it is harder for copyrighted, recently published books but do you think the authors of free albeit copyrighted texts (textbookrevolution.com) are more willing to allow me to do this?
How does cramster get away with this?
