At some point, a professor was retiring, and he had about 200 issues printed of the "ACM Transactions on Graphics", an entire book shelf. I asked and got it. The years he had were the 70's and 80's, when 3D graphics were research and transitioned from "how to render a line" to "stochastic motion blurred hyper-surface photon tracing". I used to read them as entertainment. Amazing stuff.
