first of all not all of the scrolls are pocket size.secondly,there are bibliographies in the scrolls and if you don't see one he ALWAYS will give you the name of the specfic book and author if he has used a quote or it is suggested reading on a particular subject.the problem is that most people don't READ the scrolls all the way through.or they read one,see a typo or something and dismiss everything.it's aiight though.....
