This set contains three separate boxes, colored coded. Set one is Season One and has 8 discs. Season 2 and 3 have seven discs. The back of each has a complete list of episodes with Stardates and original airdates. Very cool set in very good, used condition. There is some minor wear to the plastic boxes. 

There are no other labels or inserts, so I am not sure of the release date or company that put these out.
