The Great Hall of Family Records was an institution of the Orion Colonies. It contained the records of Orion families and was a source of Orion history.
In the 23rd century, the Great Hall of Family Records was one of a number of sources of information examined by Starfleet researchers seeking to learn more about the Klingon people and the Klingon Empire. The Klingon Bureau of Starfleet Intelligence compiled all that they learned in a briefing manual provided to Starfleet officers, edited by Captain Sara Jankowski. (FASA RPG module: The Klingons)
