For collections that come to the archive already well organized, every effort should be made to maintain this order.  Maintaining the order of collections tells something about the previous owner(s) of the materials.  In certain instances, this principle must be modified, as, for example, where preservation and storage factors may mitigate against the maintenance of original physical order.
