I sincerely think that autobiographies should be placed in the fiction section. It is the accounts of one person looking at the highlights reel spanning decades through the dusty glass of her own memories, and often has very little to do with the objective truth, if a such a thing even exists. I think all of us should revisit our planned autobiographies in our heads many times before we start writing them. Look for memories that might have been forgotten, question if you remember things correctly, find plot threads that you missed on the first reading.
