Perhaps I'm not skilled in reading sub-text,

but I thought the original post was about what type of books we would like to see in an ebook package.
Just in case that
was the case, I would like to see, apart from one's favourite fiction titles, far more non-fiction ebooks.
For example,I am have an interest in prehistory (or perhaps the old "Stone Age" classification, and before, covers it best), and would love to be able to access
a) e-versions of already published works
and
b) new writings on the subject in e-form.
But I just wish more non-fiction generally was out there....
[ I was delighted, however, to find a fascinating little offering on oriental carpets on Gutenberg, that I would never have found normally.
