Hilbert, Courant, Bourbaki, Hadley, Dieudonné, Hardy, Descartes, Cauchy... They're all there. Could last you a lifetime.
For more "recent" ones, there's https://mirtitles.org/, which specializes in Soviet era books from MIR Publishers or, as I've known them in my translated college textbooks, "Éditions MIR". Demidovich, Smirnov, Piskunov, Kolmogorov, Tarasov, Irodov, they're all there...
As an aside, look at "Cours d'Analyse de l'École Polytechnique" by Augustin-Louis Cauchy in 1821. Look at the typography, the layout, table of contents. Pretty LaTeX like if you ask me. The last paragraph of the introduction where he thanks people who've helped him... Poisson, Ampère, and Coriolis. Damn.
