It was hard to get such large items delivered to the enterprise with any regularity but Spock had managed to arrange for his package to arrive within a few weeks of it becoming available. He'd had to bribe a member of the interplanetary mail services and may have... feigned a slight computer malfunction in order to delay the ship by ten minutes but it had all been worth it.
Ignoring the confused looks from passing crewmembers, Spock didn't quite jog to his quarters, clutching the brown-paper wrapped package in as casual a way as possible.
He almost breathed a sigh of relief (but didn't because that would, of course, be un-Vulcan of him) upon reaching his quarters and sealing the door. With steady hands, he unwrapped his hard-won prize from it's casing.
Spock inhaled sharply as the embossed cover of the old-style book was revealed, it's pages heavy with the scent of knowledge.
Spock could find himself getting achingly hard as he gazed at his brand new copy of "Statistical approaches to distinct value estimation", imagining the wealth of plots and graphs and percentages contained within.
It was going to be a long night.
