I meant to post this earlier, but hopefully the first episodes are still available; this week BBC Radio 4 is doing an interesting series on language:
In this series of five In Our Time radio programmes Melvyn Bragg tells the story of the written word from its origins in the Middle East 6,000 years ago to the present day. He discovers how the technology of writing has developed: from the earliest clay tablets to paper, the printing press and beyond.
By examining and discussing some of the most important surviving texts, Melvyn and his guests explain how this most powerful of inventions has enabled the dissemination of thought worldwide. Many of the key texts discussed here are in the British Library, and the programme features extensive interviews with our expert curators.
And here‘s the British Library page, with gorgeous illustrations.
