Romulen recipes?
Its a cookbook!!
Roddenberry had a number of ideas for the film versions (apparently few of which were acceptable to film makers).
Most of them dealt with ersatz missions like “finding God” (a variation of which was used in one of the less successful films).
The film makers wanted adventure stories (like The Wrath of Khan).
The other film makers generally prevailed.
The disks (which held much less storage than modern disks) ‘probably’ deal with his later film ideas, and not the series (and despite the high number of disks, there is probably not as much text there as their numbers would suggest, for the above noted reason)
