I see, thanks for the information. I don't know well how exactly works an eBook, I mean, how to distribute chapters and things like that so I was trying to keep my books as tidy as possible, but when I open the files I really don't know where to start. x_x
And again, I wanna put emphasis on my intention not being piracy. I do download many digital content, but it's because of my government half-assed laws "against" piracy (and against my legal rights, too, it seems), that I don't feel too troubled for doing it in case of films or music (For who doesn't know, in Spain you gotta pay an extra -a very big chunk- for any digital product like CDs, films and games, because the market "assumes" you'll use illegal means to aquire other material. Yeah, my 89-yr-old granny will eMule all her CDs of Sinatra and Elvis, lol).
I'm sorry if I tickle any sensible armpit with this, but hopefully books aren't included in this and they're cheap and nice so I wouldn't illegally download them, as I said, I just wanted to backup my already purchased collection. I believe the author would feel already supported enough with me buying the book once.
