I was contacted by a member of the library staff Peter McNiece who gave be an account to the LDC. However i need to get the croups as a physical copy and i am unable to download it. So I've emailed him and will wait for reply.
It may also be worthwhile getting some of the vision bytes data into some format (say 10 - 20) tagged stories.
In the short term i may need to use XLST to transform the LDC data into Vision Byte formats, but I'll wait till I see both in their final forms.
