@youronlyone thats a pointless distinction. it can be "unauthorised" without breaking copyright law. not that i think copyright should apply for more than a few years, or to copies of works that are not being sold commercially. id be perfectly happy if we got rid of it altogether. you really think fanfic would suddenly become impossible if copyright didnt exist?
for another example of "authorised" that has nothing to do with copyright, consider "authorised biographies". its not just about (c).
