All of the Trek art books also delve into the production of TNG quite a bit, but admittedly, it is pertaining to the art facets of the production most of all. I have:
- Star Trek: The Next Generation Sketchbook - The Movies (GEN & FC)
- The Art of Star Trek
- Star Trek: The Next Generation - The Continuing Mission
- Star Trek: Action!
Also, a lot of the old Star Trek fan club magazines (before it was called Communicator) had a lot of nice articles regarding production, as well as the Star Trek: The Next Generation magazines put out by Starlog back when.
