I visited E 164/L 84 a few years back with some friends. I had mentioned that my father had ended his career in the 23 Battalion in the 1980s. One of the members disappeared and came back with some company journals. He showed me entries my father had personally made as well as other fires and incidents of the day. It was very meaningful.
The journals are the histories of the firefighters who worked and lived in that firehouse written with their own hands. Most of the entries are routine, but they do provide interesting information as well as a picture of who/what/when/where life.
It is too bad that there is not a department system or policy for indefinite storage and access to journals. Companies have enough to do and should not become libraries or public repositories, but there should be a way to maintain these pieces of history for the benefit of future company members, so they don't get stolen, lost, destroyed or sold on eBay.
