Where are the Manuals?


NeXT guy
Whre can I get the manuals for MAC OS X???
I've a whole shelf of NeXTStep manuals at home, but so much has changed since then.
Apple even seems to have removed the online help files from the more important applications. Or are they only hidden somewhere?
Can manuals be bought somewhere? I didn't find a pointer on the apple website.
Or do you have to take ceritfication courses to get the documentation like you have to with M$ software?
