I have eBook readers on Windows XP & 7 (Kindle for PC and Nook for PC), Linux Ubuntu (FBReader & Calibre) and on iOS I have iBooks, Google Play Books, Kindle, Nook and Logos & Olive Tree Bible Software Readers.
I am trying to figure out how to collect up all my books into 1 reader that allows cross platform reading. The cloud helps when picking up where I left off from another device. Each place I purchase books from likes to hide their files nested in their own readers software. How do I find the books and how do I collect them up into 1 location and 1 reader?
I have Calibre on my Linux PC and am looking at installing it on my Windows PC too which will allow me to convert files. I am leaning toward the Kindle, Nook or FBReader readers over the one that comes with Calibre based on the user interface and the versatility of the platforms.
