Earth Preservation Society

From Buck Wiki, the ultimate Buck Rogers reference

Yeah, well, your half-baked 25th-century historians got things so messed up, they don't know the difference between a cowboy and a traffic cop.

The Earth Preservation Society operates on 25th century Earth, attempting to preserve and curate Earth's lost history.

Due to the events of World War III and a holocaust that followed, as well as the dispersion of various tribes across the galaxy (BR25: "Time of the Hawk"), information from prior to those events is often haphazardly put together by historians.
