Accuracy?

How important is accuracy in fiction? I think it's very important. I try to get the "real" aspects of my stories correct because the real parts of a story, the non-ficiton aspects, help "sell" the fiction.

This is especially true when I'm weaving a tale that includes truly incredulous elements — supernatural beings, unlikely coincidences and anything in the science fiction, fantasy or magic genres.

What am I talking about? Usually, it's the setting. When I placed my vampire story, I set it in parts of New York City that I know very well. I've been told by readers that one of the best parts of Bram Stoker's Summer Sublet is the "tour of New York." I'm pleased by that, as the magical elements are integrated into real, solid, factual places.
