True, but the OP hasn't indicated either way if it's a scan or a pirate. The fact that they hasn't mentioned it tends to make me think pirate - and being a cynical Englishman tends to make me favour the latter.
They hasn't responded to any of the comments in this thread regarding this thread either. And the fact that their first ever post is a bit suspect, doesn't bode well for me helping them. Can't use past behaviour to determine this.
I agree this is refering to coding/formatting, but the inclusion of the text from a copyrighted book doesn't help. Looking at the poor level of coding in the given example makes me think it resembles being made by someone with a grasp of HTML from an earlier time before ePubs. As the book was published in 1986 seems to confirm this. So for me, this points to pirated and not a scanned book.
