Robin Good: Mobento is a hub of curated educational video clips integrating a special search engine capable of finding any word spoken inside the video collection and of visualizing where the words were spoken on a timeline.
From the official site: "This is a library and a library has librarians. That’s us. We’ll be rigorous in only uploading high quality, fascinating videos from established academic institutions and learning organizations."
