For "Micro-Film Reference", it's readable. It's the room to the left of the turbolift.
I was watching "The Man Trap", and I noticed a new sign. When we see the A-Frame, on the wall beyond this frame, there is a white directional sign with black lettering for "Officers Quarters", and it indicates that the quarters are to the right of the A-Frame. Trekcore doesn't have a screen cap of this A-Frame and the sign.
