Old books as well. I recently read some books written during the late 1800's through to World War 1 about sniping (aka long distance military shooting). It was fascinating on so many levels: - The language was completely readable. On the one hand that makes sense but on the other it's wild to read something from over 100 years ago and still find it enjoyable and get a lot of the jokes etc - Seeing a discipline still relatively in its infancy develop in combat conditions was incredibly interesting. One book in particular mentions the psychology and persuasion required to convince command to adopt new technologies and tactics At the end of the day, you realize "we're all just people" spending a large amount of our time dealing with other people. The clothes and technologies change but we still stay largely the same.
