Obviously except for your books, Mr. Rushdie, which are also very good.

Chatter, the blog of Diesel Bookstores in California, just posted a helpful list of pronunciations of authors' names (via PWKnox). I won't ask which ones you've been getting wrong if you won't.

Obvious but helpful tip: If you need to know how to pronounce a living author's name, try searching on YouTube to find video of him or her at an event saying it. Audio from NPR interviews used to be my gold standard, but some of their commentators veer off the beaten path and their subjects are too polite to correct them.
