I can’t remember if I posted this here before, but if you are interested, this discussion group about linked data was started by Laura @ Emory, Doug G @ Ga Tech and a little help from me. 

Please feel free to join us – (and it does not matter what kind of library you are in or how much you know – or don’t – about linked data – we’re all in some stage of learning.)

Also, we are interested in voices and resources outside of libraries, too (though we hope to keep the focus somewhat regional).
