Good to have your company, HB. You can share any book that doesn't carry DRM padlocking software.
Sony hardware is superb, but its library software ain't. Might be an idea for you to download the excellent Calibre Library software that most of us here use (

If you need more detailed advice, try posting in the Sony-dedicated sub forum here at MR. Luck, happy Sonying and best wishes. Neil
