Starfleet Language Conference
The Starfleet Language Conference was only featured in a deleted scene from the  second season episode .

Three books from the conference were shown in Hoshi Sato's quarters as she was packing. They were titled as followed:
Vol 1 – Monterey Proceedings – Ju 2164
Vol 2 – Tycho Conference – Ja 2166
Vol 3 – Vulcan & Andorian Vocabulary
Given that the episode was set in 2153, it is perhaps fortunate that the books did not make it on screen. The books were sold off on the It's A Wrap! sale and auction on eBay.
