any O'Reilly Book you wanna use for reference has been published online (I believe without permission from O'Reilly, because if O'Reilly wanted to do this, it would be done on the O'Reilly site.) @ www.unix.org.ua/orelly/

The rest of stuff on the site is in russian and I just cannot figure out the rest, But I see links to solaris stuff, russian edition of PC Magazine, conveniently replicated over.
