I just checked and my Seattle library has 10 times as many ePub and 10 times as many MobiPocket eBooks as this Ohio source.
IF you live in Washington State, but are not part of the Seattle library you can get a non resident card for $85 per year. Or, if you are temporarily living in Seattle, you can get a temporary card for 3 months for $25.
