Where in the World

During the past week I've been researching routes and key cities on the Persian royal road.  I've been looking for mountain passes through which my characters can travel and a port from which they'll sail.  It's more work than planning my own vacation!

Along the way, I've come across some interesting sites on old maps--though most didn't help with my current project.  Here are links to some of my favorites:

• Historic Map Works
• David Rumsey Map Collection
• Sepia Town
• American Memory Map Collection
• Historical Map Archive
