I believe there’s interest and value in combing through a writer’s archive but I also believe that whatever was deemed good enough for publication when the author made such decisions is what we should look at. Everything else is just a refection of unfinished ideas and experiments that, for whatever reason, were left behind. We need a filter to help guide us and I trust that an author’s filter should be respected.
Then, whomever writers such a book will eventually die and leave his or her papers behind for an archivist to curate. Then someone should write about he archivist and the process repeats itself, again and again.
