there is a program called calibre that allows you to change ebooks to a different reader. i always redo the pdf files to a lit file for my phone. i don't like the way pdf's look on my phone. it seems to handle all formats. i probably have a 1000 books on my pc and phone cause i just don't have room in the rv for "real" books.
i found beth ann williams celtic book in ebook format too. 11.00 download. much cheaper than print.
