I've been going through my book collection. My oldest book is from 1848: The Ferry-Man's Daughter by D.P. Kidder
In 1848, the US was experiencing the Gold Rush, we were fighting cholera epidemics, and opening our first medical school for women.
I love the history captured in these old gems. Lost language and etiquette are kept alive in printed form. It's hard to believe some of these survived through history. I feel so lucky to own these bits of history.
