BBC - Learning Zone Clips Library

I do not know how long the BBC's Learning Zone Clips Library has been available:

"The Learning Zone provides rich audio-visual material for use in primary and secondary schools and colleges. These short videos have been selected to match the curriculum; they can be used in many ways, from the stimulation and engagement of students to the delivery of very specific learning points."

You can browse by "primary", "secondary", or "colleges", although the latter category seem rather empty. There is help, which focuses on how to embed a video into PowerPoint, but which needs expanding to explain how to embed a resource in a web page, or a web-based presentation application like Slideshare, as well as into OpenOffice.
