Join historian and journalist David Mould on a journey to borders, both real and imagined in this virtual event at 6 p.m. Wednesday, Jan. 13. 

In his latest book on travel, history and culture, Postcards from the Borderlands, Mould explores the meaning of borders. Are they simply political and geographical, marked by posts, walls and fences, or should we think of them more broadly? Some borders, set by surveys and treaties, take no account of geography, language or culture. There are borders within countries — physical, economic and social. And finally, there are the borders of our minds — the way we may think of unfamiliar places.
