I might have seen something about this before, but I've lookded through a whole bunch of threads and haven't been able to find the solution!
Sony bookstore is offering 4 Science Fiction books until May 31 for free. I don't buy books from Sony so when I buy them from elsewhere I download them to my desktop and then 'drag and drop' them into Sony and Calibre. But this time when I downloaded 2 free books they went right into the opened Sony Library from their bookstore. I know I am making it sound confusing.

But now that they are in Sony library, how do I get them into the Calibre library? Sony won't let me drag them and when I go into My Documents and into My Books the only books that are there are the original free ones that I got when I first bought my PRS505 and some other ones that I have 'dragged' there.
No 2, new, free science fiction ones.

So can anyone tell me where they are on my hard drive. I looked around including doing a 'Search' and nothing comes up.
Thanks for any help that is offered.
