A crew manifest (or crew roster, passenger manifest, or even drone manifest for Borg ships) is an official list of persons known to be associated with or assigned to a large vehicle or starship. The record is usually kept for military or commercial reasons. In early history, the list would be accomplished with primitive record keeping and corroboration methods, while more advanced cultures usually use a computer interface to track the persons in question. With the inter connected ness of database software used on computers, it is usually possible for a user with clearance to go in depth and view individual personnel files for individuals contained in these lists.
