I downloaded the cia world fact book to my desktop computer and mover it to myn800 and it functions off line just fine. I have had success with this with a couple of other sites as well. I have also downloaded sites directly to the n800 as well. I have looked at html code but am not proficient at coding, but it seems that some sites will link to the local folder and some won't. It is also important to capture all the internal links.
