I had seen this about a week ago, but I got another email reminding me about it today:
The Electronic Literature Collection, Volume 1.
I’ve had a unit (off and on) in English 516 where we talk about sites like this, and as I start thinking more about planning the online version of 516 I’m going to teach in the winter, this site makes me think it’d be a cool thing to include. If nothing else, the layout is neato.
