Research History
Fred Galvin submitted a cite from a 1985 reprint of Crawford Kilian's "The Empire of Time".

We would like cites of any date from other sources.

Fred Galvin found a reference that suggests the term is used in the sense 'in or towards the past' in Ian Wallace's "Croyd Spacetime Maneouvres" series; we would like to check these books to verify this use.
