Wold Wide Phone Book

The Worldwide Phone Book contains listings for every person who has ever existed, including those yet unborn. Entries automatically update according to individual's changing life circumstances and current whereabouts. A comprehensive index by name, profession, or pastime allows users to locate anyone across space-time. Each page features 27 parallel entries per inch, arranged alphabetically within perpetual temporal flux. Discreetly hideable ink signatures verify authenticity upon calling.
