Many programmes have transcripts or factsheets online.
Check our factsheets site and whether the programme has a website with more information. BBC Education also has support materials and resources online. You can only usually get a copy of a programme if it's commercially available. Otherwise, we're sorry but we can't provide it for you. Copyright and contractual agreements only cover broadcasts - the duplication or distribution of tapes and other material has to be negotiated separately so we do this for commercial release.
