H2O Playlist: "H2O playlists are more than just a cool, sleek technology -- they represent a new way of thinking about education online. An H2O Playlist is a series of links to books, articles, and other materials that collectively explore an idea or set the stage for a course, discussion, or current event.

H2O Playlists make it easy to:

transform traditional syllabi into interactive, global learning tools

share the reading lists of world-renowned scholars, organizations, and cultural leaders

let interested people subscribe to playlist updates and stay current on their fields

promote an exchange of ideas and expertise among professors, students, and researchers

communicate and aggregate knowledge -- online and offline.

So, go on ... check out existing playlists or create your own. You can also read our philosophy behind building this technology."
