Just got three 'books' that I can't find any way to get onto my Paperwhite or HD7. If I had something with a SD slot it wouldn't help, they are just too big. Even the PCMCIA slot on my PC is too small for them. They're twice as big as my Paperwhite.
So I wind up cradling one 'book' in my hand while I read and every once in awhile I have to use my other hand to turn a page. When I want to pause I have to find something to mark my place.

Trouble is when I'm finally done with them I'll have to find some place to put them till I need them for reference again.

My ten bookcases are already full to overflowing.
So many books, so little time ...
