Thanks to user @Abcd for pointing this out. It seems that there are some books floating around the internet, selling for $4.61, that are compilations of SE answers. What are the laws regarding this, and what makes them legal/illegal (i.e. attribution)?*
*Meta posts on this: https://meta.stackexchange.com/questions/273989/are-these-ebooks-that-copy-from-se-illegal, https://chemistry.meta.stackexchange.com/questions/4217/is-publication-of-chem-se-stuff-in-the-form-of-e-books-legal. As a further note, I'm not looking for whether its legal, I'm looking for what makes it legal/illegal and where in civil law is it mentioned.
