This website delivers thousands of free academic and educational multimedia content, including videos, animations and simulations. The site’s strengths are in Mathematics and the Sciences, but also cover History, Economics, English and Religion. The videos on the site are aggregated from other American educational collections (including the Khan Academy) and arranged by broad subject areas which are then subdivided into narrower concepts, and laid out on the page in a logical and easy to follow screen display. It is slightly frustrating that there is little contextual information associated with the videos, in the form of descriptions, contributors, and other useful metadata. It is also not possible to click through to view the video on its original home page. Nonetheless, worth visiting for the range and quality of material available.
