The story caused a sensation when published and remains in print as of 2011. Revelations about the book's origin have caused much doubt as to its authenticity and factual accounts, and the publishers have listed it as a work of fiction since at least the mid-late 1980s. Although it is still published under the byline "Anonymous", press interviews and copyright records suggest that it is largely or wholly the work of its purported editor, Beatrice Sparks. Some of the days and dates referenced in the book put the timeline from 1968 until 1970.
