This is an unprocessed collection. Any arrangement reflects either a pre-existing order from the records' creators or previous custodians, or preliminary sorting performed by staff.

As much as possible, materials remained in the order in which they were received, though they were rehoused. Most records from individual buildings are together, but the buildings themselves appear to be in no particular order. The process of rehousing these began in 2019, with boxes 1 to 26 of the 100 received compressed into new boxes 1-21. However, beginning with original box 27, the materials appeared to have been sent over in a chaotic order, often unlabeled, which bore little relation to the contents list. As a result, 13 boxes were returned to Facilities, and may eventually come back to MASC, at which point they'll be treated as a new accession. The remaining 61 boxes of the materials were reboxed in Jan. 2026, forming the current boxes 22 to 57. Much of this portion of the materials were rearranged during rehousing, and significant quantities of material were discarded.
