Most of the records fall into two major categories: "Production" [data], and "Mailing list" (examples are shown in the adjacent images).

Many of the Production records show not only commodities produced, but also commodities sold or used; consumed; or shipped. There are some records of ores received (by smelters). For simplicity we categorized them all as Production records.
Other useful information you'll find in the scanned records include producer name, producer location, and mine name (these information are not included in the data dashboard).
There are also a few "Mailing memo" and "Production memo" records that are exactly what the names imply. They don't offer statistical value, but we included them nonetheless.
The records available here represent a fraction of the entire paper collection. We intend to scan and catalog additional records in the future.
