In case you haven't been to the site that hosts these, or haven't been lately, there are a LOT of areas that have now been photographed, and added to the site.
One of the recent improvements to the museum area on the second deck has been the installation of some 60" (I think) monitors that have interactive views of all these.
There's a mouse, or track ball, or other pointing device, and the public can select the area of the ship that they want to see, and "explore" it in a Virtual Reality kind of way.
These are almost all areas that are Off Limits to the public, and I haven't even been to most of them.
The fact is, at my age I don't think climbing up to the "O-12 Level" is much fun, and going all the way down into the bowels of the ship isn't much fun, either, so I'm grateful that the photographer has been allowed access to the ares, and done such a knock-out job in documenting them.
I haven't been down to the museum area in a while, so not having seen the new exhibits, I'm fuzzy on the details, but knowing the quality of work that our crew does, I'm sure it's quite impressive.
