A huge collection of very high-quality #physics, #mathematics and other #science#books from the Soviet-era Mir Publishers, available for #free #download here in the format of your choice. These are worth their weight in gold today. Their hardcover/paperback versions are next to impossible to find. They have some the best introductory, mid-level and reference #textbooks on various scientific topics that I've seen over my entire scientific career, written by some of the greatest Russian scientists and mathematicians. Check out in particular the Little Mathematics Library. Enjoy!
