Subject Matter Records
Subject Matter Records was set up in 2022 in the Twente area to keep the work of Janko Bartelink under all the names it was made under. The office of archivist is held by two, a person and a machine, and signs as one. It holds 87 records, all listed. Of a selected few I dispatch copies; you can order them through the slip on the record, which hands you to one of the archive's agents.
