Even for draft one of the western, known as The Women That Don’t Fit In, the Texas General Land Office was a huge help. Railroad maps were the best and most period-specific, but even later maps showed me the evolution of a city. Like the Nevada Digital Library, it is slooooow.
“West of Here” by Jonathan Evison is an epic story that switches between the settlement of a small town in western Washington state and it’s current-day travails. The novel alternates between the two time zones until developments near the end bring the two settings together in unexpected ways.
