Star Trek: Starship Spotter

Starship Spotter was created more than two centuries ago to serve as a reference guide to assorted space-going vessels. Captains of the spaceships of the United Earth Space Probe Agency used this simple paper tool to enable a ship's crew to quickly distinguish friend from foe in the unexplored reaches of the cosmos. When the services were merged to form Starfleet, this paper book disappeared from use. Only recently rediscovered, the newest editions of this book have been the sole purview of Starfleet Academy.
