That's a pretty impressive display, Therin - I presume all of those are new copies, or are some of them used?
Everything is new, including some rather early Titan Books UK editions of TNG and TOS numbered Pocket Books, before Titan dropped the license and the US editions were imported. On a different shelf, more early Titan Books UK editions had been reduced for clearance.
Beside me, not in shot, was a pile of the boxes of the newish, interactive, "Federation: The First 150 Years" book. In a different section, IDW trade omnibuses were well represented.
