I was just reading that book last weekend and didn't it have the year of her death listed incorrectly in the back? Before you pointed out that it was 1981, I had thought it was 1982 based on another source, and I think the book has it even later. Details, details, I know but I think it is important to get them right as much as much as possible out of respect. Of course, books are usually are not fact checked that heavily. Fleshing out the Wiki entry is a nice idea.
