Welcome to MobileRead auld.
If you haven't noticed it already, there is a special sub-forum for the
iRex iLiad.
I'm not familiar with that particular reader, but many here are, so if you have any specific questions just ask.
There is a lot of information starting at the MobileRead Wiki
Main_Page.
There are lots of free
Mobi/PRC Books, that can be read on your iRex iLiad, made by our MobileRead members.
Browse the fori and enjoy. Visit the
Lounge for some serious or silly discussion.
WDE.
