The Vulcan Ministry of Information was an agency of the Vulcan High Command during the 22nd century.
When the United Earth Starfleet decided to send Enterprise into the Delphic Expanse in 2153, following the Xindi incident, the High Command decided to transfer T'Pol from Enterprise and reassign her to the Ministry of Information on Vulcan. According to Soval, she might find her assignment at the Ministry of Information "refreshing." (ENT: "The Expanse")
