What are the oldest programming books still relevant in 2022?

By oldest, probably the Foley "Principals of Graphics" or the later, slimmer Watt "3D Graphics" are ~'30years'+

If you're considering later books, probably Perlin/Musgrave/etc.'s "Textures & Modelling", Christer Ericcson's "Physics/Collision", and Pharr/Humphries "Physically Based Rendering" are probably 3 foundational books that are quite relevant to modern programming/simulation.
