I was asked to share some yellow examples. From top left clockwise:

Dixon — After Man (fun)

Darwin — On the Origin of Species (gotta continue reading it, I will not add bookmarks anymore)

Standage — An Edible History of Humanity (currently reading this one along with a green book, so fun!)

An old NatGeo issue I got in the wrong place

Leskov — Lefty (awesome illustrations)

Hesse — The Glass Bead Game, Siddhartha + Journey to the East (vibe)

Dorren — Babel (dropped, got bored)
