This video is part of the National Mine Map Repository’s “How It’s Done” series, in which archive specialist Jessica Reitz walks through the steps involved in preserving historic mine maps.
In this episode, she demonstrates how staff humidifies rolled or brittle maps so they can be safely opened, repaired, and prepared for scanning. This process helps protect fragile documents and supports OSM’s mission to maintain accurate mine records that help safeguard people and the environment.
