She starts the article off by admonishing: “If you're an author, be careful what you leave lying around.” Then she cites two examples. First is Vladimir Nabokov who died, leaving a pile of index cards. Those cards were published as The Original of Laura -- “so faithful to the original that part of the book are reproductions of the index cards themselves, which can be punched loose and stacked.”
The second example is a Michael Crichton manuscript, which has been published posthumously. Pirate Latitudes, from the description given in the article, sounds to me like an earlier manuscript he wrote and most likely had no intention of publishing (we all have a few of those in the attic, don’t we?).
The article ends with what I think is a good question and one which we writers might want to think about as we shove that first or second manuscript under the bed.
Are a writer's heirs really entitled to strip-mine his papers for every conceivable nugget of value?
