There is a program, called Calibre ( free to download and use) that manages E-books...I have a lookbook and it isn't compatible with kindle or the nook. I have a decent size e book collection, All i had to do was add the ebooks to Calibre and hit the convert button and poof i can now read kindle books on my much less expensive Lookbook. ( i am pretty sure it converts word docs and pdfs also, but i haven't tried this as of yet.) Good luck i hope this helps.
