Even though it smells, a book which consisted of entirely lost episodes from the TNG era would be a godsend. It would be amazing to see what got pushed into production and how far on that show... especially after watching and re-watching the same 178 episodes about a trillion times!
And... a trillion times more to come on Blu ray!
Well..there is a book that with treatments to lost episodes and movies. Itīs mostly TOS...but there is also some TNG stuff in it. I donīt know if its still in print though. I donīt know the english title because I bought the german translation.
