There were 4 of the then state-of-the-art, fastest in the world, CDC-7600 and CDC-6600 computers installed at Lawrence Livermore Lab (LLL, now LLNL, Lawrence Livermore National Lab) when I worked there during the summer of 1972.
I can't claim to have it on my bookshelf anymore, but DID have the original hardcopy on my bookshelf for many years back in the 70's and early 80's when I was programming some low-level math libraries and needed to refer to some approximation techniques (e.g., Chebyshev for logarithms).
EDIT: oops, just realized that you were referring to a later version of the classic. I was referring to Abramowitz and Stegun's Handbook of Mathematical Functions with formulas, graphs, and mathematical tables (1964).
Previous posts have nicely covered almost all of the textbooks and papers I would have mentioned myself, including K&R's _C Programming_, Brooks' _Mythical Man-Month_, Feynman's Lectures, etc.
The only glaring omission was any mention of the classic (1965) FFT paper by Cooley and Tukey: "An algorithm for the machine calculation of complex Fourier series." _Mathematics of Computation_, 19(90), 297–297. doi:10.1090/s0025-5718-1965-0178586-1 (https://www.eit.lth.se/fileadmin/eit/courses/eit085f/Cooley_...)
I might also have added the _CRC Handbook of Chemistry and Physics_ that seems to have been on every working scientists's and engineer's bookshelf (including mine) during the mid-to-late 20th century. Still in print, nearing the 100th edition.
Also, some of my old favorite textbooks that I used at University were not mentioned, including Thomas' _Calculus and Analytical Geometry_. I still have my red cloth covered Addison-Wesley 3rd edition, no longer in print, but a much later edition might still be in print.
