First a requirement for this glitch is Oghma Infinium (acquired from the daedric quest 'Discerning the Transmundane') that is in your inventory and not read and a book shelf (found in breezehome after getting the alchemy lab upgrade). Save before going further. what you want to do is go to the book shelf and read the book and choose your skill set. close the book but do not exit the bookshelf. store the book into the bookshelf and then exit it. Take the book off the shelf and select the option (Do not read). repeat the process until desired.
