Over the past few years, more and more universities and colleges have created video archives of important and timely conferences, proceedings, scholarly lectures, and have placed them online. Columbia University has created this fine archive that highlights many of these types of events, with many of them featuring the scholars in residence at the school. The video forum archive features thematically bundled commentaries (usually lasting close to one hour) on a variety of topics, such as globalization (featuring Nobel Prize winner Joseph Stiglitz), and the 21st century American city, which features Bernard Tschumi and Kenneth Jackson, the noted urban historian.
