Wikipedia says: "The Benin Empire or Edo Empire (1440-1897) was a pre-colonial African state of modern Nigeria. It is not to be confused with the modern-day country called Benin." In Nigeria, Benin City still sits to mark the region, a central part of the slave-trading region of the 17th century.
I want to learn more of the kinds of world history I missed in middle and high school, either because it just wasn't taught (where do kids learn about the Benin Empire in high school history?) or because in all my moving around (five high schools, really and truly) in my youth, I missed out on some curriculum.
I collect natural history, environmental, and geography books, almost compulsively. I look for used versions where I can (to save paper) but also appreciate that many of these books come out in runs of a few thousand copies, and aren't profit-makers for the publishing companies, so when they come out new, I buy them while they're new. If you like Geographile and want to let me know, please either comment on my posts, or visit my Powell's wishlist to feed my book collection. You might find books you like there, too.
