On this German site you can find two articles about the iRex Iliad and some information about the Sony Librié and Reader.
The first article is about the "De Tijd" project and in my opinion is rather weak.
The Second article

is a bit more interesting and contains some information about the business partners iRex has, and a pretty bold claim "we built the Sony Librié, sony just did the plastic casing and the buttons"
Teleread has a brief translation, so check it out over there. if you have trouble understanding some passages then don't be shy and ask one of our german-speaking members (like alexander and me...
