The Estate Imperium is a division of the Administratum, described as "the million-strong records office of the Administratum". Presumably its purpose is to keep and furnish records of Imperial organizations. The Estate Imperium is also one of the overseers of the vast Departmento Munitorum. It is an ancient organization dating back to the Unification Wars.

帝国档案部是内务部的一个部门，被描述为“内务部的百万人档案部门”。据推测，其目的是保存和提供帝国组织的记录。帝国档案部也是庞大的军务部的监督员之一。这是一个可以追溯到统一战争的古老组织。

The division's head carries the title of Chancellor. The Estate Imperium's importance is such that its leader sometimes holds a position in the Senate of the High Lords of Terra.

该部门的负责人的头衔是总理。帝国档案部的重要性如此之高，以至于其领导人有时会在泰拉高领主参议院任职。
