Andrei Reznikov, one of the students at the Jewish People's University, posted the notes Andrei Zelevinsky had prepared for the calculus course he taught there in 1980-82.
The notes were xeroxed (a criminal offence according to the USSR legal standards) by Boris Kanevsky, who was later arrested and served a lengthy prison term on trumped-up charges.
Thank you, Andrei Reznikov, for saving the notes and making them available online!
