An acquaintance of mine - let's call him Robert - is having a book published based on his academic research. The book targets the general public, and the publication is commercial, albeit with a scholarly nature. In theory, my acquaintance could even see some money out of this affair.
Robert begins each chapter with an epigram - a short quote from somewhere. It could be an official document of some world state, it could be some adage by a famous literary figure, etc.
Now, the (US) publisher is requiring Robert to obtain explicit rights for the text of each of these epigraphs - just like other reproduced material such as photos, tables of data etc. I am pretty sure this is a bogus requirement, but I'm not sure how to advice Robert to argue against this and claim he should not need to do this.
In case it matters at all - these epigraphs appeared in Robert's relevant articles, monographs, reports and/or theses on which the book is based.
Can you help me offer such an argument?
