The TED [Technology, Entertainment, Design] conferences are known for "riveting talks by remarkable people"--Doris Kearns Goodwin, Elizabeth Gilbert, Michael Pollan, and Steven Pinker, to name a few--and all TED Talks are available for viewing at the TED site. But where to dive in?
Via @joycevalenza, here's a link to all TED Talks as of 03/31/09 on a spreadsheet that includes names of talkers, names of talks, short summaries of talks, and links to the videos. It enables one to quickly skim topics and choose a talk for viewing.
Lauren Pressley of Wake Forest University's Z. Smith Reynolds Library and her coworkers have come up with a great way to share TED Talks with staff: they have weekly, informal Wednesday Lunches with TED, watching a talk (each TED talk is 18 minutes max., by design) and then chatting about possible applications for the library.
