1 2 Asimov, Isaac. In Memory Yet Green. The date of my birth, as I celebrate it, was January 2, 1920. It could not have been later than that. It might, however, have been earlier. Allowing for the uncertainties of the times, of the lack of records, of the Jewish và Julian calendars, it might have been as early as ngày 4 tháng 10 năm 1919. There is, however, no way of finding out. My parents were always uncertain and it really doesn't matter. I celebrate ngày 2 tháng 1 năm 1920, so let it be.
↑ Asimov, Stanley (1996). Yours, Isaac Asimov. My estimate is that Isaac received about 100,000 letters in his professional career. And with the compulsiveness that has to be a character trait of a writer of almost 500 books, he answered 90 percent of them. He answered more than half with postcards and didn't make carbons of them. But with the 100,000 letters he received, there are carbons of about 45,000 that he wrote.
