I first caught this story on the BBC Breakfast news programme this morning, and was intrigued and excited to learn about these previously unreleased documents.
Later there was an item on BBC Radio 4 about the discovery (http://news.bbc.co.uk/today/hi/today/newsid_7941000/7941422.stm). It is amazing to think these records have not been available to the public, will bring hope to many searching for WW1 ancestors and other military researchers.
A slightly more detailed look at some of the records appears on the BBC News website http://news.bbc.co.uk/1/hi/uk/7940569.stm with historian Peter Barton describing some of the contents.
I shall watch this with great interest, patiently waiting for the records to appear online.
