Philip Roth vs. Wikipedia? No contest.

The prize-winning author says he's furious with the online encyclopedia over its entry about his novel "The Human Stain."

In a letter posted Friday by The New Yorker, Roth says Wikipedia editors had said the book was inspired by the life of author Anatole Broyard.

Not true, Roth responded. The character was based on the late Melvin Turin, of Princeton University.

Roth says he privately reported the error to Wikipedia and was told, to his amazement, that he needed a secondary source. So Roth made his case to the public.

His agent, Andrew Wylie, confirmed the letter was written by Roth.

By Friday afternoon, the Wikipedia entry had been updated to include Roth's comments and to note that some had "incorrectly speculated" about the novel's origins.
