[NTLUG:Discuss] good "book" format for html?

[Kevin Brannen]

I'm looking for a good format to hold books that are in HTML, something 
that can hold the HTML, including any graphics (or other files) that 
support it.  If I were in the MS world, the CHM format would probably be 
what I wanted.  But, I want to use this in Linux, so an "open standard" 
is really what I'm searching for.

Can anyone recommend anything they've seen, read about, whatever?

BTW, I'm really not searching for docbook and the other formats that 
would require me to convert the HTML into something else.  I like HTML 
because of it's simplicity and univerality.  Of course, this may all be 
for naught if there is no decent reader (and generator), but I got 
programming skilz :-) so I could create that if I can find a good enough 
standard.  Thoughts?

TIA,
Kevin
