I haven't been in school for photography in 15 years and recently was given several boxes of my college photo professor's books so I read this textbook over a couple months last year. An overview of not just the history of photography, but its role in society, its context, and how it communicates with the world at large. Tons of niche, smaller, and unexpected moments in the medium and not just "the greats". Definitely keeping this around for reference.
