This is a slideshare presentation by Beth Kanter on Curation. If you've followed this topic for a while, you've seen other great posts by Beth on Curation such as this one for NTEN but this one is an up-to-date version which is worth looking at again.
Curation is an idea that has been maturing fast recently. And it's great seeing Beth push the anlysis and highlights its specifities and best practices. She also commented this presentation and the corresponding webinar here on her blog.
