Picard's copy of The Many and the One
The Many and the One was a memoir written by Spock regarding the challenges he faced as one of the first Vulcan cadets in Starfleet.
Jean-Luc Picard owned a first edition paper book of this title, which he kept in his personal library at Château Picard. In 2401, he gifted it to Elnor upon the latter's assignment to the USS Excelsior. In response to Elnor's concern that his excitement may distract him from his studies, Picard quoted from the book: "Exhilaration enhances the absorption of knowledge.", which he explained meant "In other words, live a little."
