BBC Radio 4 now has a dedicated online program library! Rather than hunting through the site, you can now browse by subject and/or program from one main 'Collections' page. It's not all of the output by any means, but there's plenty there to keep you going, such as the philosophy archives from Melvyn Bragg's "In Our Time", or various mathematics programs from different series. There's much much more as well. [more inside]

Engines of Our Ingenuity is a web site run by John Lienhard of the University of Houston. The site includes almost 2000 short, three minute talks on the history of science, technology, and engineering. The talks are in the form of RealAudio files, with accompanying transcripts which often give you more links and references. The transcripts themselves are indexed by keywords and are also fully text-searchable. A simple idea but very effective, and kind of addictive. I've been finding out about Jacquard and Babbage, German women astronomers of the seventeenth century, and the deisgn of the zipper. There's also other cool stuff: what did people say about books in 1498?
