My question is how can I contain the PDFs that I sell to the users so they aren't distributed to their classmates or put onto filesharing sites for all to DL for free. Anyone have suggestions or should I just accept that it may happen and be happy I have sales in the first place.
My second is in regards to the copyright issues. While I am paraphrasing and condensing material from several books, at what point would there be an issue? In the fine print of one of the textbooks it says "any reproduction, including note taking is consider copyright infringement." I'm not 100% certain they can really claim everything in the books as theirs - considering this material is standardized across the industry and is part of a standardized test. I know this isn't a legal forum, but does anyone have any experience with this?
