yes, they've actually updated their website - http://www.blacklibrary.com/

They now offer print on demand of some older books, and best of all, a new Ciaphas Cain novel is announced (we knew a new Sandy Mitchell book was coming, but it had been thought a dark heresy book).

Just noticed the new Cain book will be hardback - so another year after that till the paperback

The Print on Demand books are only available direct, so I won't be able to get those through work either. Then again I already have the ones they're listing, and it looks like Insignum Astartes will be smaller than the original at only A4 format.
