I bought this, thinking it was an additional volume of episodes of the one I bought that was released in 2008. In fact, it's the same episodes, with 2 missing from the earlier edition.
Obviously, I wouldn't have bought this if I had known it was the same thing. Also, the title has been altered slightly. The first one I bought mentions the years 1962-1957. This new volume says 1961-1967, so naturally I thought new episodes were being released. So, as I said, What a Crock to the eggheads who released this in a misleading manner. Beware.
