Dinitia Smith in the New York Times:
Jacob Neusner, a mild-seeming, grandfatherly man relaxing in his easy chair, might have published more books than anyone alive. “As of this morning, 905,” he said recently. It was 4 p.m. The count was still good.
Hold it! Mr. Neusner, 72, a professor of theology at Bard College in Annandale-on-Hudson, N.Y., has just called to say there are 924. This year alone there have been 22 books, most in his field, ancient Judaism. And no, he doesn’t count revisions or translations.
Mr. Neusner studies rabbinical writings of the first 600 years A.D., when rabbinic Judaism evolved. He has translated both the Palestinian Talmud (35 volumes) and the Babylonian, twice (second translation, 46 volumes). In fact, he has translated most of the ancient rabbinic literature. The Chronicle of Higher Education has called him probably the most prolific scholar in the nation.
