Not sure why, but whatever.

You had:

src: url("res:///fonts/Gentium Plus-Bold.ttf")

where you needed:

src: url('res:///fonts/bold/Gentium Plus')

So that's that simple obvious thing I was missing! The Sony Readers always referenced actual font files, just like the regular CSS files.

Thanks! There are some small mistakes there in the Monospace section, but I am sure I can iron it out with this example to use as the starting point.
