I'm writing a style guide for programming and one of the examples I'm providing for describing what it's like to read bad code is by comparing it to reading a bad novel.
I know through experience that typesetting can greatly benefit the comfort of the reader and I would like to provide actual examples of this from other works. Am I able to provide a picture of whole pages, portions or pages, does it have to be public domain work, etc.
The information I'm interested in is the typesetting and not the actual content. I believe that someone's presentation of even public domain work has rights, which is why this is questionable. It's not the content but that person's presentation that I want to provide an example of for critique.
